DNA testing revealed that both species are more closely related to rays of the genus Mobula than previously thought.Īs a result, giant mantas were renamed 'Mobula birostris' to reflect the new classification.Īccording to the US National Oceanic and Atmospheric Administration (NOAA), the main threat to the giant manta ray is commercial fishing, with the species both targeted and caught as bycatch in a number of global fisheries throughout its range.
Until 2017, giant mantas were classified in the genus Manta, along with the smaller reef manta (Mobula alfredi). They are circumglobal and are typically found in tropical and subtropical waters, but can also be found in temperate waters. The giant oceanic manta ray (Mobula birostris) is the largest type of ray in the world, with a wing span of up to 29 feet.
