## The heaviest bony fish

The ocean sunfish holds the record as the heaviest bony fish on Earth, with the largest individuals weighing up to about 2,000 kg (4,400 lb) and measuring around 3 m from fin tip to fin tip. Its body looks like a giant swimming head that ends abruptly, because it never develops a normal tail. In place of a tail it has a rounded rudder called a clavus, formed from the back of the body.

## Help protect the Ocean Sunfish

Ocean wildlife is under mounting pressure from overfishing, bycatch and plastic pollution.
