| Abstract |
The lantern-fishes currently known as Myctophum affine constitute two distinct species. M. affine has ctenoid scales, a rounded upper opercle, PLO photophore about midway between pectoral fin insertion and lateral line, and more gill rakers. M. nitidulum has cycloid scales, an angulated upper opercle, PLO nearer pectoral insertion, and fewer gill rakers. M. affine is a smaller fish and develops caudal-peduncle luminous scales at a smaller size than M. nitidulum. No significant meristic differences were found between samples from the western North Atlantic, the Gulf of Mexico, and the Caribbean Sea. |
