The Colossal Fish!

The Ocean Sunfish are the heaviest bony fish on the planet being able to reach weights of over 2,300kg.

They can also grow to formidable sizes.  One animal that was struck by a boat off Sydney, New South Wales, Australia in September, 1908 measured 3.1m from snout tip to “tail” fin and 4.26m from dorsal fin to anal fin tip.

Mola mola held the record as the world’s heaviest boney fish, however, recent research revealed that the honour actually belongs to Mola alexandrini – the Bali sunfish.
