Sunfish (Mola Mola)

The sunfish can reach 3 meters in length and weigh up to 2300kg! This is the largest known bone fish. It is also the only one that feeds almost exclusively on jellyfish, but can also feed on zooplankton and small fish.

This unusual fish has a small brain (a 200 kg specimen has a brain the size of a walnut) and a ridiculously short tail, as it does not grow at the same rate as the body.


The moonfish does not have a fusiform body, as often happens with fish, but an oval and rough body, like that of a tortoise in the back. Although not sought, the moonfish is often confused with sharks, when nothing on the surface of the dorsal fin is exposed. The moonfish can live up to 10 years. The female can produce more than 300 million eggs, each with 2 or 3 millimeters in diameter.


Moonfish can jump out of the water, a technique they often use to rid themselves of parasites (which they always have in abundance) and to avoid predators (seals, dolphins and whales).
