With the use of ultra-high-speed videography, Ecology and Evolutionary Biology Associate Professor Emanuel Azizi and colleagues from Occidental College Los Angeles have shed light on the hunting mechanism of the cone snail Conus catus. Published online in Current Biology - Cell Press, the researchers identified the snail's hydraulically propelled feeding structure as the quickest movement among mollusks by an order of magnitude.

Most people may not equate snails with speed, but members of the aquatic species C. catus have been found to possess some of the quickest movement among the animal kingdom. While many land snails use their radula, or feeding structure, to munch on plants, members of C. catus use their chitinous radula to catch fast moving fish and other marine animals with remarkable speed. And Professor Azizi and his colleagues were interested in determining just how fast their harpooning radula could function.

"When studying movement in animals, we found that latch and muscular sphincter structures like the one found in the cone snail's hydraulically propelled radula are capable of producing movements at remarkable speeds. By...
