Tuna fisheries are primarily responsible for the drastic decrease in population of one of the most prolific and widespread shark species, the oceanic whitetip (Carcharhinus longimanus)....

An international team of scientists have used DNA to determine that groups of dusky sharks and copper sharks living in different coastal regions across the globe are in fact separate populations of each species. Both groups are heavily exploited for the shark fin trade, which claims tens of millions of animals every year to produce the Asian delicacy: shark fin soup. Many of these fish are declining rapidly as a result of pressures of fishing for their fins. The dusky shark is classified by...

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...

Photographs of fins used to ID individual sharks In the first census of its kind, research led by UC Davis and Stanford University found that there are far fewer white sharks off central California than biologists had thought. The study, published today in the journal Biology Letters, is the first rigorous scientific estimate of white shark numbers in the northeast Pacific Ocean. It is also the best estimate among the world's three known white-shark populations (the others are in...

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...
