Oarfish Facts


An Oarfish is the longest bony fish in the ocean. They can reach a length of over 50 feet. It belongs to the Regalecidae family of fishes. Unlike many bony fishes, they lack scales. Instead they have tubercules and a coat of guanine which is topped with an omate, red dorsal fin.

They are generally found in deep waters and rarely seen on the surface of water. Scientists believe that they are pushed there by storms or strong currents.  They are adapted to survive under high pressures. They got this unique name from their long pectoral fins.
