TeleosteiThe largest group of living fish, found in both the oceans and in freshwater habitats. Teleosts are characterized by a fully movable maxilla and premaxilla (which form the biting surface of the upper jaw); the movable upper jaw makes it possible for teleosts to protrude their jaws when opening the mouth. Teleosts are also distinguished by having symmetrical tails. Related category• ZOOLOGYAlso on this site: Encyclopedia of Alternative Energy & Sustainable Living Encyclopedia of History |
