The Okinawa Churaumi Aquarium houses manta rays in the "Kuroshio Sea" tank, one of the largest aquarium tanks in the world. The first manta ray birth in captivity took place there in 2007. Although this pup did not survive, the aquarium has since had the birth of four more manta rays in 2008, 2009, 2010 and 2011.
Most batoids have a cosmopolitan distribution, preferring tropical and subtropical marine environments, although there are temperate and cold-water species. Only a few species, like manta rays, live in the open sea, and only a few live in freshwater, while some batoids can live in brackish bays and estuaries.
The giant oceanic manta ray, giant manta ray, or oceanic manta ray (Mobula birostris) is a species of ray in the family Mobulidae and the largest type of ray in the world. It is circumglobal and is typically found in tropical and subtropical waters but can also be found in temperate waters. [ 4 ]
Manta rays, which feed on tiny zooplankton, funneling water into their mouth with two horn-like fins on either side of their head, are no threat to humans. They do not have barbed tails like ...

The first difference could be the size because the giant oceanic manta ray is bigger than the reef manta ray, 4 to 5 m (13–16 ft) on average versus 3 to 3.5 m (9.8–11.5 ft) on average. [7] However, if the observed rays are young, their size can easily bring confusion.
Off the coast of the island Guraidhoo (Maldives), two reef manta rays (Mobula alfredi) display a typical feeding behaviour: They swim in circles while filtering plankton out of the water.
The bizarre Lessiniabatis of Early Eocene Italy. Permineralized stingray teeth have been found in sedimentary deposits around the world as far back as the Early Cretaceous.The oldest known stingray taxon is "Dasyatis" speetonensis from the Hauterivian of England, whose teeth most closely resemble that of the extant sixgill stingray (Hexatrygon).
