The moapa dace (''Moapa coriacea'') is a rare cyprinid fish of southern Nevada, United States, found only in the warm springs that give rise to the Muddy River, and in the upper parts of the river. It is the only species of the monotypic genus ''Moapa''. A small fish, with a maximum recorded length of 9 cm, its scales are small and embedded in the skin, resulting in a noticeably leathery texture (thus the species epithet, derived from Latin ''coriaceus'' "leathery"). General body shape is standard for cyprinids, with a vaguely conical head. Moapa daces require warm water, in temperature range of 87 to 93°F. ==See also== * * 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「Moapa dace」の詳細全文を読む スポンサード リンク
