sharksScientists Provide First Large-Scale Estimate of Reef Shark Losses in The Pacific Ocean
2012-04-27 07:39:01

Tales from towed diver surveys demonstrate sobering truth about these top predators Many shark populations have plummeted in the past three decades as a result of excessive harvesting — for their fins, as an incidental catch of fisheries targeting other species, and in recreational fisheries. This is particularly true for oceanic species. However, until now, a lack of data prevented scientists from properly quantifying the status of Pacific reef sharks at a large geographic scale....

Smalleye Pigmy Sharks Get Their Glow On For Camouflage
2012-04-27 04:40:45

Jason Farmer for RedOrbit.com There are a number of sharks that have specialized light-emitting organs on their undersides that allow them to glow in the darkest depths of the ocean. In fact, according to researchers, at least 10% of all known shark species are luminous, and this ability is one of the most mysterious areas of shark biology. A new study of a tiny predator known as the Smalleye pygmy shark (Squalious aliae), led by Dr Julien Claes from the Catholic University of Louvain...

Dolphins behave uniquely. On the one hand, male dolphins form alliances with others; on the other hand, they live in an open social structure. Anthropologists from the University of Zurich detected this unusual behavior in the animal kingdom in dolphins in Shark Bay, Australia. Male dolphins in Shark Bay, Australia, display the most complex group behavior of all mammals after us humans. Studies in the 1990s revealed that two to three male dolphins cooperate very closely with each other to...

A Case Of Misidentification: Two Sharks Could Be Endangered
2012-03-28 06:59:51

Confusion of identity between two shark species may threaten the survival of both. A new and unnamed shark species originally discovered off the Eastern United States seaboard discovered by Nova Southeastern University Oceanographic Center (NSU-OC) has a cousin that shares a striking resemblance: The endangered scalloped hammerhead shark. In an article published in the April 2012 issue of the scientific journal Marine Biology, scientists have revealed the new look-alike species to be found...

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...

Shark fins are worth more than other parts of the shark and are often removed from the body, which gets thrown back into the sea. To curtail this wasteful practice, many countries allow the fins to be landed detached from shark bodies, as long as their weight does not exceed five per cent of the total shark catch. New University of British Columbia research shows that this kind of legislation is too liberal. A study published this week in the journal Fish Biology analyzes the fin to body...

The Epaulette Shark (Hemiscyllium ocellatum) is a species of longtailed carpet shark belonging to the family Hemiscylliidae, found in shallow and tropical waters off Australia and New Guinea. The common name of this shark comes from the very large and white-margined black spot behind each pectoral fin, which remind one of military epaulettes. As a small species, it usually measures under 3.3 feet long. The epaulette shark has a slender body with a short head and broad, paddle-shaped paired...

The Pilot fish is known for following large vessels and sharks, where it feeds on parasites and leftovers. Its relationship with sharks has been described as nearly symbiotic: it is extremely rare that a shark will feed on a pilot fish, and smaller pilot fish are frequently observed swimming into...
