Any one of numerous species of big, flat elasmobranch fishes of the genus Raia, having a long, slender tail, terminated by a little caudal fin. The pectoral fins, which are big and broad and united to the sides of the body and head, give a somewhat rhombic form to these fishes. The skin is more or smaller spinose. Some of the species are used for food, as the European blue or gray skate (Raia batis), which sometimes weighs almost 200 pounds. The American smooth, or barn-door, skate (R. Laevis) is also a big species, often becoming three or four foots across. The general spiny skate (R. Erinacea) is many less. Skate's egg. See Sea purse. Skate sucker, any marine leech of the genus Pontobdella, parasitic on skates. Origin: Icel. Skata; cf. Prov. G. Schatten, meer-schatten, L. Squatus, squatina, and E. Shad. Source: Websters Vocabulary
