Yeah. I have one :)
I've heard the term for a group of manta rays to be "A fever of manta rays"
MANTA RAYS ARE CARNIVORS.
Manta rays are large, cartilaginous, salt water fish in the Elasmobranchii subclass which includes sharks and skates The manta ray is the largest of the rays. They can typically be found in and around coral reefs feeding on plankton and fish larvae. To learn more about manta rays, see the Related Links.
Yes, there is a species of smaller manta rays although i cant remember what they are called of the top of my head. Pygme or dwarf manta rays come into mind. I had a dive last year with some pygme manta rays last year in australia.
Besides during breeding, I don't think manta rays really bite. They capture food through their gills so they don't need to bite anything to eat. As far as teeth go, manta ray teeth are referred to as vestigial which basically means they are almost useless so I would say that I manta bite would not be that painful, no. Most mantas are not aggressive towards humans. We are a curiosity to them but they don't see us as a threat.
although mata rays have tails, they are NOT barbs, they are not poiseness nor electrical
because manta ray feeds on some of the smallest creatures in the oceans
Manta rays don't have stingers. They have tails.
The IUCN lists the Manta Ray as Near Threatened.
Manta Rays lack a stinger in their tale, therefore they do not sting. but from stories I've heard they can bite.
The manta rays are up to 14 feet in length, while their fin span is 20 feet.
