The sucking disc begins to show when the young fish are about 1 cm (0.4 in) long. When the remora reaches about 3 cm (1.2 in), the disc is fully formed and the remora can then attach to other animals. The remora's lower jaw projects beyond the upper, and the animal lacks a swim bladder. [9] Some remoras associate with specific host species.
The common remora (Remora remora) is a pelagic marine fish [3] belonging to the family Echeneidae. The dorsal fin, which has 22 to 26 soft rays, acts as a suction cup , creating a vacuum [ 4 ] to allow the fish to attach to larger marine animals, such as whales, dolphins, sharks, and sea turtles.
One of the whalesucker's most outstanding traits, shared among the Echeinedae family, is an adhesive disk. The adhesive disk is a round, oval, sucking disk located on the top of a remora's head, with two layers of lamellae that allow for the remora to stick and unstick to the epidermal surfaces of larger fish, mainly cetaceans.

Remora are specially adapted to attach themselves to larger fish (or other animals, in this case a sea turtle) that provide locomotion and food. Commensalism is a long-term biological interaction ( symbiosis ) in which members of one species gain benefits while those of the other species neither benefit nor are harmed. [ 1 ]
