Manta rays (cartilaginous elasmobranch) are sea creatures directly associated with all sharks.
Presently, 2 species of manta rays are known: giant manta rays (Manta birostris) and reef manta rays (Manta alfredi). They vary from each other in a number of ways, like dorsal and ventral pigmentation, grain of skin and morphology of denticles, amount of teeth, and existence of a spine/stinger.
Contrasts can be found also in their habits, size at adulthood, size of the exterior sexual organs and form of their body.These creatures are among the biggest species of fish.
These creatures are among the biggest species of fish. Wing spans of the massive manta can go over 7 meters, and weight as much as 2 tons, and also wing spans for reef mantas tend to be about 5.5 meters, getting weights of as much as 1.4 tons.
Manta rays can be found all over the world, but are more typical on warm ocean waters. Both species reside in the open sea, going to reefs to get nourishment and be washed.
The giant manta is much more extensively dispersed, growing in warm, sub-tropical and also temperate ocean waters. These are effective at migrations of over one thousand kilometers, telling huge home range capacities.
