Using physical experiments and computer modeling to explore the efficiency of bladed tooth shape Using a combination of guillotine-based experiments and cutting-edge computer modeling, researchers at the University of Bristol have explored the most efficient ways for teeth to slice food. Their results, published today in Journal of the Royal Society Interface, show just how precisely the shape of an animal's teeth is optimized to suit the type of food it eats. There is a massive variety...

Sawfish Behavior Leads To Species Own Decline
2012-03-06 05:58:15

[ Watch the Video ] A team of researchers led by Barbara Wueringer of the University of Queensland, Australia have been studying the feeding habits of the freshwater-dwelling sawfish Pristis microdon. The researchers found that when the sawfish feeds, it uses electrosensors in its long snout to detect the location of the prey in the water. The sawfish swipes, several times per second, at its prey with a side to side motion with enough force to saw the fish in half. The sawfish would...

Image 1 - Shark's 'Denticles' Help It Achieve Higher Speeds
2012-02-09 13:47:34

Researchers have found that razor sharp tooth-like scales known as denticles found in a shark's skin actually help the fish swim faster. The denticles are thought of to behave like the dimples on a golf ball, disturbing the flow of water over the surface to help reduce the drag and increase the thrust. "What we found is that as the shark skin membrane moves, there is a separation of flow — the denticles create a low-pressure zone, called a leading-edge vortex, as the water moves...

2011 Shark Attacks Remain Steady, Deaths Highest Since 1993
2012-02-08 05:13:22

[ Watch the Video ] Shark attacks in the U.S. declined in 2011, but worldwide fatalities reached a two-decade high, according to the University of Florida´s International Shark Attack File report released Tuesday. While the U.S. and Florida saw a five-year downturn in the number of reported unprovoked attacks, the 12 fatalities – which all occurred outside the U.S. – may show tourists are venturing to more remote places, said ichthyologist George Burgess, director of...

Australia Waters Harbor Hybrid Sharks
2012-01-03 08:09:49

Marine scientists from the University of Queensland have discovered hybridized sharks off Australia´s east coast, leading them to believe that some of these predatory beasts display a tendency to interbreed, challenging long-standing scientific theories regarding shark behavior. This is the first time scientists have confirmed a substantial number of hybrid sharks off Australia´s coast, speculating that it may be an adaptation or reaction to climate change; and scientists now...
