INDIAN RIVER COUNTY — Five people were rescued Saturday in two separate incidents, after being swept out to sea by powerful rip currents at Round Island Park beach.

One of the five was a woman, taken to Indian River Medical Center as a precaution after inhaling water.

“She was in a critical situation,” said 23-year-veteran ocean lifeguard Aaron Levy. “In my opinion, she would have drowned.”

Levy’s partner, lifeguard John Dotsey, pulled her to safety.

A man and woman who had tried to help her also were pulled from the ocean by Levy after being caught in the rip current.

Later Saturday, a 13-year-old girl and her father, a recent Army veteran were rescued by lifeguards, Levy said.

He compared rip currents to a river that pulls people out to sea. Levy said the currents remain strong even though last week’s big waves are subsiding.

He recommended always swimming near a lifeguard.

If caught in a rip current, remain calm and swim parallel to shore to escape it, he added.

Oregon man reports encounter with great white shark | statesmanjournal.com | Statesman Journal

COOS BAY — An Oregon man says a great white shark knocked him off his surfboard near Winchester Bay.

David Lowden told “The World” newspaper in Coos Bay that he was paddling his board last week near the south jetty of the Umpqua River when a shark he estimated at nearly 14 feet broke the surface behind him.

“As I’m flying off the board, I got a good look at the shape of the shark,” said Lowden, who was not injured in the encounter.

The shark emerged halfway from the water and broke the fins off his surfboard.

“That probably scared it a bit. It thrashed around a bit … and after that it disappeared,” he said.

Lowden, 29, and another man surfed to the beach while a third surfer, Lowden’s friend, Mark Lorincz, of North Bend, clambered onto the jetty and ditched his board.

Lowden phoned the U.S. Coast Guard to report the encounter, then contacted the Shark Research Committee, a private group that tracks shark attack data.

A release from that organization characterized it as an “unprovoked shark attack.” It was the only recorded attack this year in Oregon, and the fifth along the Pacific Coast.

Alan Shanks, a professor at the Oregon Institute of Marine Biology in Charleston, said the encounter described by Lowden is typical shark behavior.

Shanks said great white sharks often attack from below to stun seals, sea lions and other large prey.

“These guys are primarily big-thing eaters,” Shanks said. “A surfboard from below has a silhouette not unlike a marine mammal.”

Lowden said local surfers frequently see sharks. He has spotted six sharks while surfing on the Oregon coast, including one that bumped his board in 2006.

“I wasn’t that surprised, to tell you the truth,” Lowden said. “It’s not the first time I’ve had an encounter.”

Shark attack: Incredible pictures of 30 great whites stripping a whale carcass provide ‘extraordinary’ insight into eating habits | Mail Online

Ever since Jaws, great whites have had a reputation as killing machines that has never seemed much point questioning.

However, that could all be about to change – after a study into the fearsome predators’ dining habits.

Scientists towed a 36ft Brydes whale carcass into a well-known hunting ground for the animals in an exercise aimed at documenting how they tackled the huge free lunch.

And these amazing pictures show how up to 30 of them stripped a single whale carcass – and gave an ‘extraordinary’ insight into how the much-feared predators behave.

But while many would have expected a feeding frenzy and potentially lethal fights between the razor-teethed gians, the behaviour observed was quite different.

The sharks appeared to select choice cuts of the dead whale and did not appear to be aggressive towards each other.

Free lunch: The 30 great white sharks were provided with a whale carcass so scientists could study their eating habits

Tasty findings: Alison Kock was the principal scientist at Save Our Seas Shark Centre and Shark Spotting Programme, at Cape Town in South Africa and was surprised by the sharks

Alison Kock, 33, the principal scientist at Save Our Seas Shark Centre and Shark Spotting Programme, at Cape Town South Africa, said: ‘Contrary to their reputation as mindless killers, the level of selectivity for which parts of the dead whale they ate was extraordinary.

‘They targeted the energy-rich blubber, often making repeated “test bites” where no flesh was removed, and removing flesh only once they had determined it was what they wanted. If they got a mouthful of muscle, they often spat it out.

‘They were very picky.’

It’s thought the huge whale was killed after being struck by a boat and was found floating towards Miller’s Point near Cape Town, South Africa, where the clean up operation for the local authorities would have been difficult as their huge bodies are harder to remove on land.

It was also feared the body – giving off oils that attract predators like sharks – may have drawn in great whites to an area frequented by swimmers.

Kock added: ‘Permission was granted by the authorities to have the dead whale towed to nearby Seal Island where the carcass was less of an issue and the sharks could help solve the clean-up problem.

‘In addition it provided an unparalleled opportunity to document white shark behaviour and record the number of sharks in the area.

‘Whale carcasses are believed to be a very important source of food for white sharks with some scientific evidence suggesting they follow whale migrations possibly to, opportunistically feed on dead or sick whales.’

Jaws: Alison Koch said: ‘Contrary to their reputation as mindless killers, the level of selectivity for which parts of the dead whale they ate was extraordinary’

Blubber: During the nine-day experiment Kock and her team made some shocking discoveries, including the fact that the sharks seemed to have a huge preference for soft blubber over tough muscle

During the nine-day experiment, which ended on Saturday, Kock and her team made some shocking discoveries, including the fact that the sharks seemed to have a huge preference for soft blubber over tough muscle.

‘In the case of the whale carcass the sharks knew exactly what they wanted,’ said Kock.

‘It provides evidence that when they bite into a surfboard, or kayak or person wearing a wetsuit they can immediately determine it’s not something they want to eat.

‘It’s very common in attacks on humans for white sharks to take a single bite and leave it at that. Our study provides more evidence that they are simply tasting and looking for meat that is nutritious. It shows that they are not just swimming around mindlessly eating everything they come across, as they are sometimes portrayed.’

She added: ‘I was surprised at the total number of white sharks that fed on the dead whale over the nine days we documented the event. We recorded over 30 different sharks in total. At one stage we had up to four white sharks feeding simultaneously on the carcass.

‘The first two days were the busiest with the most sharks, and the activity slowly decreased as the sharks had their fill. The last two days we recorded no sharks feeding on the carcass.

‘Many of the sharks I recognised as individuals hunting seals around the island from this shark season, as well as previous years. We used their unique dorsal fins to identify them, but there were also new sharks that I had never seen before.

‘The sharks showed very little aggression towards one another in the presence of such a large food source, often feeding side by side.

‘Some of the sharks we observed were gorging on the blubber and you could actually see their bellies getting fuller.

“Some would arrive quite skinny and by the end of their session they looked pregnant with their bellies bulging.’

During the study, the sharks reduced the carcass down to less than seven feet (two metres) of bone and muscle, having removed all the blubber.

Shark enthusiast Kock, added: ‘This is the ultimate example of the very important role sharks play in the ecosystem. That of recycling life, and of keeping our oceans healthy by removing dead and decaying animals like dead whales.’

White Shark Sightings On The Rise On East Coast : NPR

White Shark Sightings On The Rise On East Coast : NPR.

From NPR, I’m Ira Flatow.

Over the last few years, there have been more and more confirmed shark sightings at beaches on the East Coast, and this summer is no exception. Just last week, lifeguards closed part of Rockaway Beach, that’s here in Brooklyn, after surfers spotted a shark.

Further north, officials closed a remote beach in Cape Cod when a spotter of planes saw not one, not two but at least three great white sharks lurking near the shore a couple weeks ago. No one’s been allowed in the water since then.

And then just yesterday, Cape Cod’s Chatham Harbor was closed to swimming due to the sighting of a 14-foot great white shark. Scary, huh?

But before you call in Quint and his too-small shark boat in “Jaws,” to put this in perspective, there hasn’t been a fatal shark attack in New England since way back in 1936. So why are we spotting so many more great whites today?

Is their population growing, or are we just more paranoid and getting better at spotting them? Here to sort out some of the facts from fiction is my guest. Greg Skomal is a senior biologist at the Massachusetts Division of Marine Fisheries in New Bedford, Massachusetts. He joins us by phone. Welcome to SCIENCE FRIDAY, Dr. Skomal.

Dr. GREG SKOMAL (Senior Biologist Massachusetts Division of Marine Fisheries): Thank you, Ira. It’s good to be here.

FLATOW: Good, thank you. Are there more sharks these days, or are we seeing more of them?

Dr. SKOMAL: I think it’s a function, it’s a number of variables we’re dealing with here, and it’s hard for us to really tell if there’s more sharks or just simply more effort.

Certainly, a lot of the sightings along the East Coast of the United States have to do with more people utilizing the shoreline, utilizing the water for various recreational activities and otherwise.

But in think in some areas, specifically off the coast of Chatham, Massachusetts and Monomoy Island, we are indeed seeing more white sharks. And I think what we’re seeing is a shift in distribution of the white shark in that particular area.

FLATOW: And what is attracting them to that area?

Dr. SKOMAL: Over the course of the last couple of decades, we’ve been seeing a steady increase in the number of gray seals and a growing gray seal, resident gray seal population in that area. I believe it’s drawing these sharks closer to shore.

FLATOW: And why would we be seeing more gray seals now?

Dr. SKOMAL: Well, back in the early ’70s, we passed the Marine Mammal Protection Act, and it’s taken the last few decades for this population to actually recover to levels that pre-existed before we eradicated the species over the course of the last several decades. So we’ve got a growing population in response to protection by the U.S. and state governments.

FLATOW: So I guess what you’re saying is that we’re seeing a restoration of this coastal ecosystem to the way it used to be.

Dr. SKOMAL: Exactly, at least that’s the way we perceive it at this time. You know, we could be going back to what existed several hundred years ago, with a robust seal population being preyed upon by a robust white shark population.

FLATOW: 1-800-989-8255. We’re talking to Greg Skomal about the sightings of great white sharks along the East Coast. Maybe if you’ve seen one, you’d like to call in and talk about it. You can also Twitter us, send us a tweet @scifri, @-S-C-I-F-R-I. Or join the discussion on our website, on sciencefriday.com.

You, what do we you know, aside from watching “Jaws” and all the scary movies about sharks and Shark Week on cable channels everywhere, how much do we really know about white shark populations?

Dr. SKOMAL: Well, there are certain parts of the world where you can predictably find white sharks. And these areas, which include, you know, the Pacific Coast, California, parts of South Africa and South Australia – these are areas where scientists have had the luxury, if you will, of going out and studying these animals at great levels.

And we’ve been able to garner quite a bit about their biology in those areas, I think. One of the spots that we know very little about the white shark is the Atlantic Ocean. And perhaps, this change in ecosystem that we’re going through up here in New England, may begin to provide us some access to these animals so we can start to tease away some aspects of their biology.

FLATOW: And you are involved in tagging sharks, are you not?

Dr. SKOMAL: Correct, correct. Yeah, last year we had a chance, for the first time, to put satellite-based technology tags on white sharks in this area, and we are already getting insights into their biology from those tags.

And already this year, we’ve placed four tags out, and we hope to be able to continue to do that over the course of the next month.

FLATOW: How do you get, you know, how do you know when it is time to reopen these beaches that have been closed?

Dr. SKOMAL: Well, you know, the local municipalities are in charge of those beaches, and all we can do at the Division of Marine Fisheries is provide information to those folks who are making these decisions.

You know, we’d like to provide real-time information on the presence of sharks as acquired through our research activities so they can make well-founded decisions on opening and closing beaches.

FLATOW: What are the odds of getting bitten by a shark?

Dr. SKOMAL: Well, you yourself indicated that the last fatal attack in Massachusetts was back in the 1930s. So that gives you a sense of what the probability is. That being said, I think it’s important to realize when you place people in close proximity to the prey of sharks, namely gray seals, you could potentially increase the risk modestly.

So I think it’s important for people to make wise decisions when getting in the water and choose areas that may be free of white shark prey.

FLATOW: Henry(ph) in Aurora, Illinois. Hi, welcome to SCIENCE FRIDAY.

HENRY (Caller): Hello there. Being landlocked, I just have an idea that possibly, there’s less fish out there for the sharks to feed on because you could ask any fishermen why are they still in port. And the sharks will wander farther around, looking for food. That’s my idea. Thank you.

FLATOW: You’re welcome.

Dr. SKOMAL: Well, I’ll tell you, that’s an interesting point, and it points to fisheries management and population management and the importance of looking at bait species and to find relationships between sharks and their prey and whether or not we’re, you know, overexploiting their prey and forcing sharks to other areas to exploit other resources.

That being said, I think it’s well-defined, the behavior of the white shark, when it comes to feeding, these animals are clearly going through, clearly prefer larger prey, namely marine mammals and specifically seals and sea lions.

So I think what we have going on off the coast of New England is actually just a national predator-prey relationship and not anything exacerbated, perhaps, by humans.

FLATOW: Let’s go to Roy(ph) in Sumter, South Carolina. Hi, Roy.

ROY (Caller): Hi, thank you so much for taking the call and specifically on this topic. It’s always been an interest. I’ve been recreational fishing in the Atlantic for 30 years. And over the last three or four years, we’ve noticed a tremendous increase in the number of small sharks that we’re catching.

It used to be something, we may catch one shark every two or three trips, and now we probably catch 10 sharks every trip. These we refer to them as bonnetheads. I dont know if that’s an accurate terminology, about a three, three-and-a-half-foot long shark, always catch them on the bottom, never catch them trawling. And I’ll take my answer off the air, but again, thank you so much for this topic.

FLATOW: All right. Could there be many big sharks because there are a lot more little sharks now?

Dr. SKOMAL: Well, you know, the bonnethead is indeed a species. It’s considered to be a healthy population off the Southeastern U.S., according to the fisheries’ statisticians. It’s not a fish that’s heavily exploited commercially, although it is sold in some numbers, and recreational fishermen like to catch it, as well.

You know, there are some folks who believe – some scientists who believe that with the removal of very, very large sharks that consume these smaller sharks, we’re seeing more species, you know, more smaller sharks out there. That may be the case, although it hasn’t been clearly demonstrated by scientists.

So it’s an area where there is quite a bit of work, but we have no real conclusions yet.

FLATOW: Have sharks been over hunted?

Dr. SKOMAL: In certain parts of the world with certain populations, absolutely. We have enough information on, for example, the dusky shark to indicate that that population off the Eastern U.S. has been overexploited and reduced dramatically.

The same is true for the sandbar shark. For other populations of sharks, they continue to be robust, and I think the bonnethead falls into that.

FLATOW: All right, let me go to Mark(ph) in New Britain, Connecticut. Hi, Mark.

MARK (Caller): Hi, thanks for taking my call. As you said, I’m in Connecticut, and I’ve noticed changes in the water temperature of Long Island Sound. It’s been creeping up, year over year, and I’m wondering if the climatic changes, increases in ocean temperature, are a possible source of increased activity.

FLATOW: Good question.

Dr. SKOMAL: Yes, an excellent question, one we anticipate a lot of research trying to answer over the course of the next decade. We know that with climate change and global warming, we’re going to see changes in the structure of fish populations in terms of the diversity of species, with a shift north of tropical species.

And it has been demonstrated for some, already. I imagine with warming water temperatures in Long Island Sound, you’re going to see a change in the fish diversity in that body of water, as well.

So, you know, it’s an area that we’re going into. We anticipate changes, and some of them have been documented. In terms of sharks, we haven’t seen any kind of dramatic shift as of yet, but some of the species that typically occur south of Cape Cod and not north, have indeed been starting to creep around the Cape. So we’re starting to see some indications that the fish populations, including sharks, are changing.

FLATOW: Steve(ph) in Cambridge, Mass. Hi, Steve.

STEVE (Caller): Hey, how are you doing? Thanks for taking the call. Great show. I think the shark thing is just a bunch of media hype, frankly. I mean, it just, you know, it makes people tune into the news shows, and I’m not sure there’s any more or less. I just think the sightings are more – maybe because there’s more fishermen out there.

But I was wondering if you might know why there’s a lot more jellyfish in the bay this year.

(Soundbite of laughter)

Dr. SKOMAL: Well, you bring up a couple of excellent points, and a lot of the shark phenomenon, or shark frenzy, if you will, is driven by the media – and it’s something we have to deal with all the time.

I can tell you that some of the shark sightings data absolutely indicate a shift that’s going on over with white sharks, and some of it’s just generated by a media frenzy. Somebody sees a fin, it may not be a shark fin, but it gets reported as such, and that just compounds upon itself.

I wish I could be of more help with you with jellyfish. I’ve been hearing a lot of folks complain about jellyfish in the bay over the last several weeks, but unfortunately, I study things a lot bigger.

FLATOW: All right, we’ll have to take a look at that, with some jellyfish folks, on a future program. But I want to thank you for taking time to be with us today.

Dr. SKOMAL: Oh, my pleasure. It’s great to be here.

FLATOW: Have a good weekend.

Dr. SKOMAL: Yes, you, too.

FLATOW: Greg Skomal is a senior biologist in the Massachusetts Division of Marine Fisheries in New Bedford, Mass., and he was joining us by phone from there.

When we come back, we’re going to switch to electric cars, plug-ins. Do you want a plug-in? How about a Chevy Volt or a Nissan Leaf? We’re going to compare the two. Maybe you could talk to us about what you’d like to see the perfect plug-in to be. What would you are these two cars the kind you might purchase? If not, what do you want to have?

Our number, 1-800-989-8255. You can tweet us @scifri, @-S-C-I-F-R-I, or go to our website at sciencefriday.com, where you can chat around with some folks that way.

So stay with us. We’ll be right back after the break.

(Soundbite of music)

FLATOW: I’m Ira Flatow. This is SCIENCE FRIDAY from NPR.


Coyote attacks girl in N.S. national park

A teenaged girl was attacked by a coyote while sleeping at a campground in Nova Scotia’s Cape Breton Highlands National Park early Monday, Parks Canada says.

Cape Breton RCMP said a 911 call was received around 4:30 a.m. and was attended to by Parks Canada.

The girl suffered two bite wounds to her scalp. She was treated at a nearby hospital and released later in the morning.

“It’s difficult for us to say exactly what happened. It doesn’t appear that the bite was provoked by anything the person did,” said Derek Quann, resource conservation manager with Parks Canada. “It’s important to mention that she was in a sleeping bag outside of her tent, close to the tent, when this occurred.”

Parks Canada considers this a “serious incident,” Quann said.

The agency is working to increase awareness among visitors about coyote behaviour and how to stay safe in the event of an attack. Efforts are also being made to attract the animals into an area where they can be safely and humanely trapped, Quann said.

The Department of Natural Resources said it has received a record number of calls from the public about coyotes since last fall, when Taylor Mitchell, a 19-year-old folk singer from Toronto, died after being attacked in the national park by two of the animals.

Mitchell’s death triggered warnings about coyote safety in the park. Parks Canada organized open houses to inform hikers about coyote behaviour to try to prevent future attacks.

This spring, the province announced that it would keep 15 trappers on call to deal with complaints about aggressive animals. Coyotes found near communities would be captured and killed, the province said.

The government also announced in May it would start paying trappers $20 per coyote pelt when the trapping season begins on Oct. 15.

There are an estimated 8,000 coyotes in Nova Scotia. Provincial officials say as many as 4,000 could be killed by next spring.

Great white sharks in SoCal waters may not be so rare – The Daily Breeze

Posted: August 10th, 2010 | Author: | Filed under: sharks, wildlife | Tags: , , , , , , , , , , , , , | No Comments »

For years, a running joke among swimmers and surfers frequenting Los Angeles County beaches has been that they had more to fear from a mild sunburn or parking ticket than a possible encounter with a hungry shark.

But no one is laughing in New England, where a recent string of great white shark sightings has prompted beach closures.

Or in San Diego, where a swimmer was attacked and killed by a white shark in April 2008.

But in waters off local beaches, white shark sightings are relatively rare. Or are they?

Experts, pointing to relatively new tracking technology, say the massive creatures are migrating down the coast to Baja California, through Santa Monica Bay.

Waters off Los Angeles County beaches are also a congregating place for their offspring.

“There is a known occurrence in the summer of juvenile great white sharks in Santa Monica Bay,” said Steve Blair, an assistant curator with the Long Beach Aquarium of the Pacific.

Blair said he was unaware of any shark attacks on humans in the area and it’s difficult to pinpoint specific migration tendencies among white sharks – including why they tend to linger off local coastal waters.

“They’re hard to study because they’re so large – you can’t handle them or catch them easily,” Blair said. “And they’re really not that common.”

The species has been protected in California waters since 1994, according to the California Department of Fish and Game.

Experts say white sharks, which were added to international endangered species lists in 2004, like to feast on fish and seals, rather than oceangoers as depicted in the 1975 film “Jaws.”

Most attacks on humans, they say, stem from curiosity or mistaken identity – sharks mistaking a wet suit-clad surfer for a seal, for example.

Revelations about the white shark’s migration down the Southern California coast have been made possible through the efforts of researchers at the Monterey Bay Aquarium who have been tagging white sharks off Ventura and Los Angeles beaches and monitoring their movement.

Based on tracking data, sharks are swimming through waters from Santa Barbara south to Mexico, said Ken Peterson, a Monterey Bay Aquarium spokesman.

Since the program began in 2002, about 38 juvenile white sharks have been tagged off Southern California coastal beaches.

Waters off Will Rogers State Beach and Malibu have historically been known to attract white sharks, Blair said.

“There are certain areas they’re attracted to,” he said. “Any areas that include large populations of seals and sea lions.”

Sightings have also been reported near San Onofre State Beach in northern San Diego County, Huntington Beach, the Channel Islands and throughout the Central and Northern California coast, including the Farallon Islands off San Francisco.

Despite the sightings, attacks on humans are rare.

But websites dedicated to forecasting surf are rife with user-submitted notices of alleged shark sightings throughout the Santa Monica Bay.

“They’re frequently incorrect,” Blair said. “Sharks are commonly misidentified.”

Los Angeles County lifeguard officials said there have not been any recent shark sightings off South Bay beaches.

During the past two decades, there have been a string of shark sightings in waters off South Bay beaches, highlighted by a sighting in July 1978 of a rare hammerhead shark near the Manhattan Beach Pier.

In 2008, stunned whale watchers gathering at the Point Vicente Interpretive Center in Rancho Palos Verdes watched as a great white shark attacked a sea lion from underneath, throwing the animal in the air before crushing it with its jaws, according to a report in the Daily Breeze.

And in August 1982, two commercial shark hunters snagged a 16-foot female great white shark off Point Dume near Malibu.

The shark, too large to put aboard their boat, was towed to San Pedro, where a large crowd gathered to see the shark weighed. It died on the journey back to the harbor.

“All this just because of the movie `Jaws,”‘ one of the fishermen, Craig Williams, said while the massive creature hung on display for the growing crowd. “It’s not really that big a deal.”

Woman: Shark took me for a ride – News

BETHUNE BEACH — As Judy Fischman swam in the Atlantic Ocean here Thursday, she suddenly found herself lifted above the water on the back of a large dark animal.

“My first thought was ‘I hope this is a manatee,’ ” Fischman said Friday. “Then I saw the black tail.”

“Shark,” she thought. “Then I saw other sharks and I thought, ‘My God, how am I going to escape a whole group of sharks?’ ”

From her vantage point on the street overlooking the scene, Martha Williams wondered the same thing.

Williams and her husband Ron had stepped out of their car to look out at the ocean. They first noticed a woman swimming alone, a couple hundred feet off shore. It was about 7:15 p.m. Then, as they watched, she said sharks appeared in the water, swimming parallel to the shore between the beach and the lone swimmer.

“I said to Ron, ‘Oh my God, I hope they totally ignore her, just don’t even see her.’ Then all of a sudden they all veer off and they’re all heading to her,” Williams said Friday. “I about screamed and said, ‘Oh my God, oh my God, they’re heading right to her, right to her.’ ”

As they watched, the ocean surface around Fischman erupted in churning water and the swimmer was suddenly lifted above the surface of the wave, arms and legs flailing, she said. “It was just so frightening.”

Back in the water, Fischman said she realized she “was on the back of a huge shark. There was another shark next to me.”

“I screamed,” she said, “but I don’t remember what I screamed.”

Fischman said she remembered advice she’d seen on television for fighting off sharks — giving them “a good punch and let them know you could hurt them.” She started punching the animal. As it seemed to roll on its side, she said it seemed to sort of wrap its tail around her.

“Then a wave came. All of a sudden they were gone,” she said. “They probably realized I’m not food and let go.”

“Maybe they thought I was a seal,” she said. “I had on a black bathing suit.”

Ron Williams ran down to the beach expecting to find the swimmer in need of medical attention, but instead she walked back to shore.

“It was really something,” Martha Williams said.

Fischman told her story to a Beach Patrol officer Thursday night, and on Friday afternoon, Fischman and Martha Williams spoke with George Burgess, director of the shark attack file at the University of Florida. Burgess isn’t yet sure what kind of animal surfaced under Fischman. He said it could have been a shark, or it could have been some kind of dolphin or small whale.

Williams and Fischman agreed to fill out witness statements for Burgess and he’ll try to figure out whether it was a shark encounter.

“It was possible it was a shark attack,” he said. “It’s also possible it was an encounter with a marine mammal.”

Sharks were spotted elsewhere in Volusia and Brevard counties on Thursday.Volusia’s Fischman swims regularly for exercise and said she often sees sharks. She likes to swim far enough out to get past the breakers, in water not quite 6 feet deep.

Fischman, a Bethune Beach resident since 2002, figured maybe a guardian angel was watching out for her. She emerged from the encounter with nothing but scrapes on her legs. And, she headed right back into the water on Friday afternoon.

She’s also had some close encounters with manatees during the past couple of years. “It’s very startling,” she said. “You can get lifted out of the water.”

Tourist believes he was bitten by a tropical sea snake off the coast of Cornwall | The Sun |News

Posted: July 24th, 2010 | Author: | Filed under: snakes, wildlife | Tags: , , , , , , , , , , , , , , | No Comments »

Shocked Dan Muldowney was left in agony, bleeding and feeling dizzy for ten days after the attack.

The 4ft creature sank its fangs into his bare shin while he was bodyboarding on holiday with his family – leaving a double puncture wound.

It also bit him on the thigh but failed to penetrate his knee-length wetsuit.

Dan, 27, who believes he was the victim of a tropical species normally found in the Pacific and Indian Oceans, said: “I felt something like a clump of seaweed against my leg, then a bang.

“When I looked in front of me I saw a snake with a black head shaped like a cobra – I clearly remember seeing its wide neck. No sooner had I seen it than it was gone.”

The attack at the popular resort of Newquay came just weeks after a fisherman saw a sea snake swimming at Whitsands in south-east Cornwall.

Dan, a surveyor, was enjoying a break with girlfriend Kenize Akhtar and their four children when he was bitten.

At the time he was in chest-deep surf trying out a new wetsuit he had just bought.

To begin with he thought he had hit his leg on a sharp rock and seen a huge eel.

But his wound began bleeding heavily and within ten minutes he was out of breath.

The following day blood started oozing from his mouth and he felt so unwell he was on the verge of collapse.

Then lumps like bubbles appeared on his leg and his fingertips began to tingle.

He consulted a GP, who was baffled by his symptoms, before a second doctor sent him to hospital where he was given allergy tablets.

By the time he returned home to Oldham, Gtr Manchester, he had headaches and twitching muscles.

Dan said: “My nerves were an absolute mess. I was irritable and unable to cope. Some days I just stayed in bed.”

Hospital tests failed to show anything conclusive but 12 days after his ordeal Dan started to recover.

After doing research he is sure he was attacked by a yellow-bellied sea snake. The creature’s venom, used to kill fish, is ten times more lethal than an Egyptian cobra’s.

Dan dismissed suggestions that he might have been bitten by an adder which had fallen off cliffs into the water.

He said: “There is a report of a Chinese man attacked by a sea snake who took 77 hours to die and his symptoms were the same as mine. I just want to warn other people.”

Experts said British coastal waters were too cold for sea snakes to occur naturally but that Dan might have been bitten by one which was DUMPED.

A Marine Conservation Society spokeswoman said: “If someone had kept a sea snake and let it go, potentially it could survive.”
