Giant Oceanic Manta Ray - Maximum mass (tonnes): 3.0

The largest kind of ray in the world is the Gigantic Oceanic Manta Ray (Mobula birostris), sometimes known as the giant manta ray or oceanic manta ray. Although it can be found in temperate seas as well, it is mainly found in tropical and subtropical regions. The species, along with the more diminutive reef manta ray, was categorized in the genus Manta up until 2017. Both species are more closely linked to rays of the genus Mobula than previously believed, according to DNA analysis. As a result, to better reflect the new classification, the big manta was given the new name Mobula birostris.

The huge oceanic manta ray can reach lengths of up to 9 meters (30 feet) and a diameter of 7 meters (23 feet), and it weighs roughly 3,000 kg (6,600 lb) although the typical average size is 4.5 m (15 ft). It features broad, triangular pectoral fins on either side of the disc and is dorsoventrally flattened. It has two cephalic fins, which are the pectoral fins' forward extensions, on the front. When swimming or when the animal is feeding, they can be flared out to direct water into the wide, forward-facing rectangular mouth.
