Brett Smith for redOrbit.com - Your Universe Online Named after its long whip-like tail, the thresher shark uses its eponymous feature not only to swim, but also to strike at prey. An international team of marine biologists has captured and analyzed rare videos depicting the sharks' unusual hunting style, according to a report in the journal PLoS ONE. Shot in the tropical waters off the coast of the Philippines, the videos show pelagic thresher sharks accelerating toward schools of...

By Danielle Torrent, University of Florida A new study led by a University of Florida researcher uses tracking data of three shark species to provide the first evidence some of the fish swim directly to targeted locations. Researchers found tiger and thresher sharks showed the ability to orient at large distances, with tiger sharks swimming in direct paths at least 4 miles away and reaching specific resource areas about 30 miles away, said lead author Yannis Papastamatiou, a marine biologist...

Researchers, writing in the Journal of Animal Ecology suggest that some shark species have "mental maps" of their ranges and can pinpoint locations in the ocean up to 30 miles away. Tagged with acoustic transmitters, scientists analyzed data from tiger sharks, and found that they took directed paths from place to place, AFP is reporting. Using nine Blacktip reef sharks and 15 Threshers which had been tagged with trackers and released off Hawaii, Palmyra atoll in the Pacific or southern...

The rising demand for shark fin soup in Asia is spurring illegal fishing and contributing to a plunge in stocks, according to a report on Monday. The Australian government and the wildlife trade-monitoring network Traffic, published the study urging governments to crack down on illegal catches. Registered legal shark exports totaled $310 million worldwide in 2005, up from $237 million in 2002. "As the world's demand for sharks continues to grow, shark populations are plummeting," the report...

It's hard to study a creature when you only catch fleeting glimpses of it. Up until recently, that was one of the big stumbling blocks for marine biologists and ecologists, but advances in electronic tracking technology have allowed them to peer farther across, and deeper under, the surface of the oceans than ever before. Satellite tracking systems and acoustic sensors are giving researchers insights into the behavior and lifestyles of some very elusive animals in the ocean, including the...

NEW ORLEANS (AP) -- An international decision that it's illegal to cut the fins off of a shark and then dump the carcass is a great first step, but more is needed to protect sharks, experts say. The biggest need is an international limit on the number of sharks which can be killed each year, agree William Hogarth, director of the National Marine Fisheries Service, and Sonja Fordham of the Ocean Conservancy, an environmental group. Without catch quotas, the finning regulations will only slow...

The long-tailed thresher shark, Alopias vulpinus, is a thresher shark inhabiting tropical and temperate waters worldwide. Like all thresher sharks, it has a very long upper lobe of the caudal fin, sometimes as long as the body. Its body is brown or grey with a white underside. They can grow to about 25 ft in length and 750 lb. Thresher sharks often hunt in groups or pairs, stunning their prey with their tails before feeding on it. They mostly eat other fish and squid, but have been known to...
