Manta ray (Great Barrier Reef)

The genus Manta contains two species of manta rays: the Reef Manta Ray (Manta alfredi) and the Giant Oceanic Manta Ray (Manta birostris), which are the largest species of the rays in the family Mobulidae, and the largest rays in the world. Oceanic mantas reach at least 7 metres (23 ft) in width and there are anecdotal reports of even larger specimens, while reef mantas reach about 5.5 metres (18 ft) in width.
