The megamouth shark is a rare shark and a large species, reaching weights of 2700 pounds (1215 kg).However, it is the smallest of the three species of filter-feeding sharks, behind the whale shark and the basking shark.
The megamouth shark gets its name from its remarkably large, circular mouth.The megamouth has a brownish-blackish color on top and white underneath, a broadly rounded snout, and a distinctively large head with rubbery lips.They can grow to 18 feet in length. The capture in a drift net of a megamouth shark in California in 1990 was very important in understanding the species.
