Weevers (or weeverfish) are 9 extant species of fishes of family Trachinidae, order Perciformes. They are long (up to 37 cm), mainly brown in color, and have poisonous spines on their first dorsal fins and gills. During the day, weevers bury themselves in sand, just showing their eyes, and snatch prey as it comes past, which consists of shrimp and small fish. Weevers are unusual in not having swim bladders, as do most bony fish, and as a result, sink as soon as they stop actively swimming. With the exception of ''T. cornutus'' from the southeast Pacific, all species in this family are restricted to the eastern Atlantic (including the Mediterranean). A tenth, extinct species, ''Callipterus speciosus'', is known from the Monte Bolca lagerstätte of the Lutetian epoch. Weevers are sometimes used as an ingredient in the recipe for ''bouillabaisse''.〔Jean-Louis André, ''Cuisines des pays de France'', Éditions du Chêne, 2001〕 Weevers are sometimes erroneously called 'weaver fish', although the word is unrelated. In fact, the word 'weever' is believed to derive from the Old French word ''wivre'', meaning serpent or dragon, from the Latin ''vipera''.〔(''The American Heritage Dictionary of the English Language'', Fourth Edition )〕 It is sometimes also known as the viperfish, although it is not related to the viperfish proper (i.e., the stomiids of the genus ''Chauliodus''). In Australia, sand perches of the family Mugilidae are also known as weevers. ==Species== The 9 extant species in two genera are: * Genus ''Echiichthys'' * * Lesser weever, ''E. vipera'' (Cuvier, 1829) * Genus ''Trachinus'' * * Spotted weever, ''T. araneus'' Cuvier, 1829 * * Guinean weever, ''T. armatus'' Bleeker, 1861 * * Sailfin weever, ''T. collignoni'' Roux, 1957 * * ''Trachinus cornutus'' Guichenot, 1848. * * Greater weever, ''T. draco'' Linnaeus, 1758 * * Striped weever, ''T. lineolatus'' Fischer, 1885 * * Cape Verde weever, ''T. pellegrini'' Cadenat, 1937 * * Starry weever, ''T. radiatus'' Cuvier, 1829 * Genus ''Callipterys'' Agassiz 1835 * * † Monte Bolca weever, ''C. speciosus'', from the Lutetian 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Weever」の詳細全文を読む スポンサード リンク
