Remora

Remora, any fish of the Acanthopterygian genos Echeneis, with several species, from temperate and tropical seas, most abundant in the Pacific and Indian Oceans. They are called Sucking-fish, from the fact that the first dorsal fin is modified so as to form an adhesive disc on the top of the head, by which they attach themselves to larger fish, turtles, and even ships. E. remora is found in the Mediterranean.
