Body shape (shape guide): elongated.
Most abundant remora in warm waters (Ref. 4389). Occurs near as well as far from the coast (Ref. 5217). Often found free-swimming in shallow inshore areas and around coral reefs (Ref. 26938). Attaches temporarily to a variety of hosts including sharks, rays, large bony fishes or sea turtles, whales, dolphins and also to ships. May follow divers (Ref. 9710); reported to attach itself to a diver's leg (Ref. 57809). Feeds on small fishes, bits of its host's prey and host's parasites (Ref. 26938). Juveniles occasionally act as reef station-based cleaners, where they service parrotfishes (Ref. 40095). Sometimes used by natives to aid in fishing; a line is tied to the caudal peduncle of the remora and then is released; upon attaching to another fish, the remora and its host are hauled in by the fisher (Ref. 9682).
