For every type of fin, there are a number of fish species in which this particular fin has been lost during evolution (e.g. pelvic fins in †Bobasatrania, caudal fin in ocean sunfish).
The fish develop their truncated, bullet-like shape because the back fin, which is present at birth, never grows.

The anal fin moves more extensively than the dorsal fin.

The Molidae comprise the family of the molas or ocean sunfishes, unusual fish whose bodies come to an end just behind the dorsal and anal fins, giving them a "half-fish" appearance. They are also the largest of the ray-finned bony fish, with the southern sunfish , Mola alexandrini , recorded at 4.6 m (15 ft) in length [ 3 ] and 2,744 kg (6,049 ...
