Remora is dark brown or black colored.
Remora has long, flattened head and short body covered with smooth scales.
Remora has oval sucking disk on top of the head that consists of numerous paired, crosswise oriented plates. Sucking disk is actually modified dorsal fin.

Remora does not have swimming bladder. It uses sucking disk to attach itself to the body of other fish or marine creatures and to travel in the ocean. This technique also ensures swift movement of water through the gills that is vital for the normal breathing.
Depending on the species, remora can travel attached to the body of sharks, rays, swordfishes, marlins, sea turtles or large marine mammals such as dugongs and whales.
Remora eats leftovers of its host's meals and collects parasites, bacteria and dead, epidermal tissue from the surface of the skin. That way remora keeps the skin of its host clean and healthy.

Fishermen often use remoras for capturing the fish and sea turtles. They attach the fishing line to the remora's tail, release the fish into the water and wait until it attaches to the shell of sea turtle or to the body of some large fish. Both animals then need to be carefully pulled out of the water.
