It was first discovered near kaneohe, hawaii, in 1976, and it is the only living species in family megachasmidae (order lamniformes). It grows up to 7 metres in length and is a filter feeder, alongside the whale shark and basking shark Instead of relying on teeth, megamouths are filter feeders, meaning they sift out small plankton (like krill) from the water Including the megamouth, there are three species of filter feeding sharks—the whale shark and the basking shark round out the bunch. Megamouth remains one of the world’s most rarely seen sharks, and it’s amazing a fish that size could remain undiscovered for such a long time You can learn more about megamouth from the florida museum of natural history’s megamouth page.
They are likely diurnal following swarms of krill, from the surface of the open ocean during the day, and diving deep at night Megamouth has probably been encountered more times than documented but fishermen likely release them due to their immense size. The megamouth shark (megachasma pelagios) is one of the rarest and most mysterious sharks on earth
