The Ocean Sunfish, or Mola Mola, is the heaviest bony fish in the world, with adults weighihg in at 1 tonne. The word “mola” is Latin for millstone, and the fish is named this due to the flat and round shape, grey colour and rough skin. The Ocean Sunfish is in the same family as pufferfish and porcupinefish, and like the rest of this family, has four fused teeth that form a beak. They use this beak to feed on small fish, jellyfish, squids, crustaceans, and salps. Ocean Sunfish produce the most eggs in the animal kingdom, able to produce up to 300 million eggs at a time. Sunfish fry look more similar to other species of pufferfish than to adult Mola Mola.
