SkaTES, RAYS and FISH
In addition to sharks, the
Class Chondrichthyes also contains a number of skates and rays. In these
animals, the pectoral fins are greatly enlarged to form "wings" that
undulate gracefully during swimming, and the tail fin is reduced or
absent. Skates and rays differ from sharks in having few scales and
being generally adapted for feeding on bottom-dwelling animals.
Although skates may have small teeth, those of rays are plate-like and
adapted for crushing prey.
