Some commonly eaten prey includes zooplankton, krill, shrimp, and crab larvae. This process is known as aplacental viviparity and is quite commonly seen in the reproduction of a number of shark and ray species. Also, measures to address bycatch of the species in industrial fisheries are rare.
Manta rays live predominantly in tropical and subtropical salt waters, while stingrays can also be found in warm temperate waters, as well as some species living in freshwater habitats.

Manta rays are exclusively pelagic, while stingrays are generally demersal, preferring to dwell on the bottom of the ocean floor Cephalic fins: Manta rays reproduce by ovoviviparity with the birth of one pup during a breeding season.Diet.
Manta ray is primarily a plankton feeder, but also consumes small fishes. Its two cephalic lobes are unrolled and held at a downward angle to create a funnel guiding prey into its mouth. Manta ray, also called devil ray, any of several genera of marine rays comprising the family Mobulidae (class Selachii).
Flattened and wider than they are long, manta rays have fleshy enlarged pectoral fins that look like wings; extensions of those fins, looking like a devil’s horns, project as the cephalic fins from the front of the head. Manta Ray is among the largest creatures swimming in oceans, being next to sharks and whales in size.
