What is "trachinus vipera"

Weever \Wee"ver\, n. [Probably from F. vive, OF. vivre, a kind of fish, L. vipera viper. Cf. Viper.] (Zo["o]l.) Any one of several species of edible marine fishes belonging to the genus Trachinus, of the family Trachinid[ae]. They have a broad spinose head, with the eyes looking upward. The long dorsal fin is supported by numerous strong, sharp spines which cause painful wounds.

Note: The two British species are the great, or greater, weever ( Trachinus draco), which becomes a foot long (called also gowdie, sea cat, stingbull, and weaverfish), and the lesser weever ( Trachinus vipera), about half as large (called also otter pike, and stingfish).
