Lawrence LeBlond for redOrbit.com - Your Universe Online Researchers from University of Delaware are in the midst of a multiyear study with Delaware State University researchers to better understand the behavior and migration patterns of sand tiger sharks. In the latest phase of the study, an underwater robot is being unleashed to hunt down and follow these seemingly placid predators. The Oceanographic Telemetry Identification Sensor (OTIS) is a remote-controlled underwater device that...

Research Suggests Ecotourism May Help, Not Harm, Wildlife
2012-03-10 06:31:14

A new study investigating the impact of ecotourism activities that use food to attract wildlife for observers has discovered that the booming business does not appear to have a negative effect on those creatures. In fact, researchers at the University of Miami's (UM) Rosenstiel School of Marine & Atmospheric Science have discovered that the opposite may very well be true -- ecotourism may be good for the creatures that are becoming so highly sought after by would-be onlookers. Their...

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...

Hit-and-run attacks by sharks can be solved with a new technique that identifies the culprits by the unique chomp they put on their victims, according to a University of Florida researcher and shark expert. In a method analogous to analyzing human fingerprints, scientists can make identifications by precisely comparing shark bites to the jaws and teeth of the powerful predators, said George Burgess, director of the International Shark Attack File, which is housed at UF's Florida Museum of...

Sandbar, dusky and tiger sharks are among dozens of shark species living in the coastal waters off the U.S. East Coast. Little is known about many of the species, but a survey begun nearly 25 years ago is helping scientists and fishery resource managers to monitor shark populations and their role in marine ecosystems.NOAA scientists from the Northeast Fisheries Science Center (NEFSC) lab in Narragansett, R.I., recently conducted their ninth coastal shark survey from Florida to Delaware. ...

HONOLULU (AP) -- Thanks to the movie monsters, every swimmer is keenly aware that the ocean is filled with more than harmless little fish. And Leeward Oahu residents say they have seen more sharks since a fish farm took up residence about two miles offshore at Ewa Beach almost six years ago, said William Aila, a resident and fisherman. Since companies have approached the Waianae community during the last year with plans for new aquaculture farms off their coast, residents want to find out if...

The Bull shark, Carcharhinus leucas, also known as the Bull whaler, Zambezi River shark or colloquially Zambi, is common worldwide in warm, shallow waters along coasts and well-known for its unpredictable, often aggressive behavior. They have a tolerance for fresh water that is unique among marine sharks, and can travel far up rivers, posing a threat to those who venture into the water. As a result they are probably responsible for the majority of attacks on humans that take place near the...

The tiger shark, Galeocerdo cuvier, one of the largest sharks, is the only member of the genus Galeocerdo. Mature sharks average 10 to 14 ft (3.25 to 4.25 m) and weigh 850 to 1400 lb (385 to 635 kg). It is found in many of the tropical and temperate regions of the world's oceans, and is especially common around islands in the central Pacific. This shark is a solitary hunter, usually hunting at night. Its name is derived from the dark stripes down its body, which fade as the shark matures....
