EAST LANSING, Mich. — Historically, the media have been particularly harsh to sharks, and it’s affecting their survival.

The results of a Michigan State University study, appearing in the current issue of the journal Conservation Biology, reviewed worldwide media coverage of sharks – and the majority isn’t good.

Australian and U.S. news articles were more likely to focus on negative reports featuring sharks and shark attacks rather than conservation efforts. Allowing such articles to dominate the overall news coverage diverts attention from key issues, such as shark populations are declining worldwide and many species are facing extinction, said Meredith Gore, MSU assistant professor of fisheries and wildlife and the School of Criminal Justice.

Stories about croc attacks are just as terrible as they are hopeless. Experts say that it is possible to stay to fight off a shark, but it is much more difficult or even impossible to rescue themselves from an attacking croc. (more…)

It turns out the old saying is right — the nose really does know. And when it comes to sharks, the nostrils are particularly discriminating.

Combined with the ability to detect underwater vibrations, sharks are able to zero in on the location of their prey by smelling in stereo, according to a new study by researchers at the University of South Florida (USF) and Woods Hole Oceanographic Institution (WHOI).
