A remora (pronounced /ˈrɛmərə/), sometimes called a suckerfish or sharksucker, is an elongated, brown fish in the order Perciformes and family Echeneidae.[1][2][3] They grow to 30–90 centimetres long (1–3 ft), and their distinctive first dorsal fin takes 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.

Oh, SE.
