Common Remora - Remora remora
This Remora are sometimes called Sharksucker and is known to attach itself temporarily by its modified dorsal fin used as a sucking disc to various hosts, such as sharks, rays, large bony fishes, sea turtles, whales, dolphins, ships, and even sometimes scubadivers
The common remora, ''Remora remora'', is a pelagic marine fish belonging to family Echeneidae. ''R. remora'' is different from other remoras in the family Echeneidae by the modification of its dorsal fin. The dorsal fin, which has 22 to 26 soft rays, acts as a suction cup, creating a vacuum to allow it to attach to larger marine animals, such as whales, dolphins, sharks, and sea turtles.
