Remora

The remoras, sometimes called suckerfishes, are a family of ray-finned fish in the order Perciformes. They grow to 30–90 cm (0.98–3.0 ft) long, and their distinctive first dorsal fins take the form of a modified oval sucker-like organ with slat-like structures that open and close to create suction and take a firm hold against the skin of larger marine animals.[3] By sliding backward, the remora can increase the suction, or it can release itself by swimming forward. Remoras sometimes attach to small boats. They swim well on their own, with a sinuous, or curved, motion. For more information, visit the Wikipedia entry Get back to Perciformes

Live sharksucker

phylum	Chordata	The live sharksucker or slender sharksucker is a species of marine fish in the family Echeneidae, the remoras. The species is considered as circumtropical, as it occurs in all tropical and warm temperate waters around the world. Its body is elongated and streamlined. The jaws, vomer and tongue have villiform teeth. The main distinctive feature to distinguish from other fishes is the oval-shaped sucking disc, which is a highly modified dorsal fin positioned from the top of the head to the anterior part of the body.
