The easiest way to distinguish live fish is by the presence of dark spots on the ventral surface medially between the gill slits of the Alfred Manta. The Giant Manta Ray and Alfred Manta, Manta alfredi, can be distinguised by a number of measurements but also by size, dentition and spine morphology. Long thought to have been a single wide-ranging species, Mobula birostris, the genus is now known to comprise two species. Two species of Manta are known from Australian waters. Giant Manta Rays are grey-blue to green-brown above. They have a very broad mouth, on either side of which are prominent fleshy extensions called cephalic lobes. The surface of the body is rough to touch. The species has one dorsal fin and a whip-like tail which lacks a sting. The disc of the Giant Manta Ray is wider than it is long. The Giant Manta Ray is the largest species of ray in the world.
