Tadpoles kill by supersuction. (Zoology).Tadpoles Tadpoles are a psychedelic rock band formed in 1990 in New York City by Todd Parker (guitars/vocals) and Michael Kite Audino (drums.) In 1992, Nick Kramer (guitars/vocals), David Max (bass) and Andrew Jackson (guitars) of the fledgling Manhattan group, Hit, joined the Tadpoles of African dwarf clawed frogs catch their prey by a surprising means. Tadpoles typically work their elaborate, jagged mouthparts over a surface, making a soup of the scrapings. Pumping movements of the mouth cavity gently pull in and filter the resulting slurry. Researchers discovered something quite different when they turned a high-speed video camera on young Hymenochirus boettgeri not quite 3 millimeters in length. These tiny tadpoles rely on a superfast suction technique to catch prey such as minuscule water fleas, say Stephen Deban at the University of Utah The University of Utah (also The U or the U of U or the UU), located in Salt Lake City, is the flagship public research university in the state of Utah, and one of 10 institutions that make up the Utah System of Higher Education. in Salt Lake City and Wendy Olson of Dalhousie University in Halifax, Nova Scotia For other uses, see Halifax.

In the Nov. 7 Nature, the researchers report that the tadpoles track each prey individually and then suddenly extend their tube-shaped mouths to suck in to draw into the mouth; to imbibe; to absorb. See also: Suck the prey within 7 milliseconds. (For video, see http://socrates.berkeley.edu/~deban/hymenomovie.html.) Although larvae Larvae, in Roman religion Larvae: see lemures. of certain fish also hunt this way, the researchers were intrigued to discover that a quite different animal had evolved the same approach.--S.M. |
