Genus Remora


Remoras use their cephalic sucking disc to attach themselves to a range of marine hosts, including sharks, rays, large bony fishes, marine turtles, whales and dolphins.
Individuals attach to the body, in the mouth or gill cavity. They are rarely free-swimming are usually captured with their host.

Identifying features: body moderately elongate, depth 5-8 times in standard length (SL); cephlic sucking disc large with 15-28 lamellae; pectoral fins rounded; pelvic fins broadly attached to the abdomen; anal-fin short-based with 18-28 fin rays; caudal fin forked in juveniles, emarginate to truncate in adults; colour uniform - not striped.

All four species in this genus are widely distributed and have been recorded in Australia, mostly in warmer waters.
