簡単な記述
形態学 | 形態計測学
Merodoras is diagnosed from all other doradids by having midlateral plates with medial thorns directed ventrally in adults, and from all doradids except Physopyxis cristata by having an incomplete lateral line. Merodoras also is diagnosed by the unique combination of the following characteristics: pectoral girdle entirely exposed ventrally, with the opening for the arrector ventralis inferior reduced to a small fossae on anterior edge of coracoid; caudal fin truncate; dorsal-fin spine smooth, without serrae; lacrimal serrated; lateral ethmoid serrated (Ref. 58340)
