MOLA-MOLA FISH

A sunfish, also called a mola, is any fish in the genus Mola (family Molidae). The fish develop their truncated, bullet-like shape because the back fin, which is present at birth, never grows. Instead, it folds into itself..

The Mola mola is one of the largest bony fish in the world. It was misidentified as the heaviest bony fish, which was actually a different species, Mola alexandrini. Adults typically weigh between 247 and 1,000 kg (545 and 2,205 lb).
