remora

(rĕm`ərə), any of the several species of warmwater fishes of the family Echeneidae, characterized by an oval sucking disk on the top of the head. With this apparatus (a modification of the dorsal fin) the remora, or suckerfish, attaches itself to sharks, swordfishes, drums, marlins, manta rays, whales, and sea turtles. In this way it travels without effort, feeding on scraps from the prey of these larger creatures and in some cases on their crustacean parasites. Remoras sometimes attach themselves to small boats, but they can also swim well on their own. The adhesive power of their sucking disks is so great that the natives of some tropical regions use remoras to catch sea turtles by attaching lines to their tails. Different species prefer different hosts. The whalesucker, Remora australis, is usually found attached to whales; the spearfish remora, Remora brachyptera, prefers swordfishes and billfishes. The common remora, or sharksucker, which reaches 3 ft (90 cm) in length and attaches itself to sharks. Remoras are classified in the phylum ChordataChordata
, phylum of animals having a notochord, or dorsal stiffening rod, as the chief internal skeletal support at some stage of their development. Most chordates are vertebrates (animals with backbones), but the phylum also includes some small marine invertebrate animals.
