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.

[24] The fish, spotted near Lady Elliot Island, is the world's only known pink manta ray. [25] [26] M. alfredi with mouth closed, cephalic fins rolled and ventral surface showing distinctive markings
Unlike some other remora species, parasitic copepods comprise a negligible part of the diet of the white suckerfish, suggesting it may not have a mutualistic relationship with its host. [6] The white suckerfish responds to a touch on its belly by forcefully erecting its pelvic fins, possibly an adaptation to avoid crushing by its host. [5]
