Ground-breaking research by Jonathan Werry, from the School of Environment at Griffith University, found the Nerang River upstream with its less salty water and supplies of mullet to be the perfect creche for young bull sharks.
Read moreFollowing an initiative taken by Palau, the Pacific republic of the Marshall Islands will ban trade in shark products and commercial shark fishing throughout its waters.
Read moreA joint research effort between the University of Hawaii at Mānoa's Hawai'i Institute of Marine Biology(HIMB), University of Tokyo, the Japanese National Institute of Polar Research and the University of Florida has shed new light on the hunting b
Read moreThe world’s sharks are disappearing. These fearsome yet charismatic fish continue to fall victim to overfishing and many are now at risk of extinction as a result.
Read moreSeveral theories have been put forward by experts as to why white sharks sometimes bite people. In this article we examine three of the most prominent theories and look at why most of these incidents are non-fatal.
Read moreSharks are known to "dive" frequently through the water column and many functions have been attributed to the behaviour, such as thermoregulation, search and reduction of the COT.
Read moreUntil the 1990s, only two kinds of orcas were seen in the inshore waters of British Columbia, says John Ford, a zoologist at the University of British Columbia and a research scientist at the Pacific Biological Station run by Fisheries and Oceans
Read moreGiant basking sharks like to take tropical vacations too.
Read moreIt turns out that sharks can detect small delays, no more than half a second long, in the time that odours reach one nostril versus the other. When the animals experience such a lag, they will turn toward whichever side picked up the scent first.
Read moreA team of researchers led by Jason Blackburn of the University of Florida sampled and tested 134 fish living in coastal waters of the Gulf of Mexico, Belize, and Massachusetts for signs of drug-resistant bacteria, using a suite of twelve common an
Read moreHopes that shark cartilage would prove to be a useful treatment for cancer were not borne out in one of the most rigorously designed and executed studies of an alternative therapy ever conducted.
Read more"Shark tourism is a growing phenomenon but unfortunately shark populations are not," said WWF- Australia's Reef to Rangelands Policy Manager Nick Heath.
Read moreWhile the use of the liver as an energy store and for buoyancy is well documented in adult sharks, this study provides the first evidence of a decline in liver mass of newborn sharks, from 20% of body weight at birth to 6% when they start to feed
Read moreAs of July 1st, the Hawaiian State Government has become the first in the world to ban the possession, distribution and sale of shark fins and its already sending ripples to the rest of the world.
Read moreThe researchers observed 340 attacks by great whites on fur seals within 2km of Seal Island, in False Bay, South Africa.
Read moreUntil now, ancestors of modern sharks from 374 million years ago were the oldest known creatures to have both rods to see in dim light and cones, for bright light.
Recently, the genome of the elephant shark, Callorhinchus milii, a chimaerid holocephalan, has been sequenced and therefore becomes the first cartilaginous fish to be analyzed in this way. The chimaeras have been largely neglected and very little is known about the visual systems of these fishes.
By searching the elephant shark genome, Hunt's team have identified gene fragments encoding a rod visual pigment and three cone visual pigments. It also has two copies of the long-wavelength cone pigment gene, a duplication which may have given them trichromatic vision like primates.
