(Mola mola) a fish of the order Plectognathi. In the adult stage, the deep, strongly compressed body has no apparent tail section. The dorsal and anal fins are very tall. The body measures up to 2.5 m long and weighs over 500 kg (sometimes as much as 1,000 kg). The ocean sunfish is extremely fertile, laying up to 300 million eggs (only small numbers of which survive). The larvae have long, threadlike growths on their bodies. Ocean sunfish inhabit warm seas; in the USSR they are found infrequently in the Sea of Japan (near Vladivostok). They feed on plankton and small fish. Ocean sunfish have no commercial value.
