Manta Ray


Charlie Cross




     The largest of all of the rays, the manta ray, is around 22 ft. wide (6.7m). They are of the genus manta and the species birostris. They are a dark brown or black on the top of their backs and white on their stomachs. Manta Rays are located between 35˚ N and 35˚S. Their disc is the largest part of the body which holds the head and usually has the pectoral and ventral fins. 



Predator Adaptations 

     Manta Rays are prey to the Great White Shark  and the Killer Whale mainly. They are being hunted by these two animals even more due to the depletion of other food that these two animals used to eat but has become sparse because of climate change and depletion of their habitat. They are also easy prey because unlike the Sting Ray they do not sting so they can't protect themselves. The Manta Ray has adapted to be a predator by adapting to have the plates that keep organisms in their mouth so they can eat them. Also the Manta Ray has adapted to be a predator by growing cephalic lobes under their mouth which help direct food into their mouth.


Prey Adaptations

     Manta Rays have adapted to be filter feeders, which means that they suck water into their mouth and they filter out the water and pass it out through their gills while the organisms are kept inside the mouth. Manta Rays feed mostly on plankton and other smaller sea organisms such as crabs and shrimp. A very intersesting fact about Manta Rays and how they eat is that they are able to remember what feeding grounds have the most organisms that they can eat. They then return to that feeding ground and keep returning just because of that first time that they had lots of food there, this can benefit them and hurt the Manta Ray and hurt it too.The Manta Ray has adapted as prey by adapting their body shape to resemble the sea bed so that predators don't see them. Also it has adapted to be able to constantly swim so that they can get away from predators and avoid them before the predator can tell that they're there.



     The Manta Ray can be compared to the Stingray not only because they are both rays but also because they both eat the same thing and are both filter feeders. they are different from the Stingray because they do not sting while a Stingray does.


Simbiotic Relations

     The Manta Ray has a commencalistic relationship with Remoras. Much like sharks, the Remora hides under Manta Rays, they get protection from predators and they also get food from the bacteria and organism on the Manta Ray's body. The Manta Ray gets to be cleaned in return for the protection.
