The four-eyed fishes are a genus, ''Anableps'', of fishes in the family Anablepidae. They have eyes raised above the top of the head and divided in two different parts, so that they can see below and above the water surface at the same time. Like their relatives, the onesided livebearers, four-eyed fishes only mate on one side, right-"handed" males with left-"handed" females and vice versa. These fish inhabit freshwater and brackishwater and are only rarely coastal marine. They originate from lowlands in southern Mexico to Honduras and northern South America. ==Species== There are currently three recognized species in this genus: * ''Anableps anableps'' (Linnaeus, 1758) (Largescale foureyes) * ''Anableps dowei'' T. N. Gill, 1861 (Pacific foureyed fish) * ''Anableps microlepis'' J. P. Müller & Troschel, 1844 (Foureyes) 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「Four-eyed fish」の詳細全文を読む スポンサード リンク
