Manta birostris - The giant oceanic ray, measuring up to 9 meters in width and weighing 1,350 kilos, is the largest of the rays. It has huge pectoral fins, yet a relative short tail and dorsal fin. Similar to most giants of the ocean, the ray feeds mainly on tiny planktonic creatures. The krill, shrimp, and crabs are filtered from the water after passing through a specialized structure in the animal’s mouth. The oceanic ray usually bears one offspring after a 12 month gestation period. The pup is hatched inside the female and born fully developed.
