Manta Ray | The manta ray is a large species of flattened fish, closely related to other cartilaginous fish such as sharks.
The manta ray is the largest species of ray in the world with some
manta ray individuals reaching up to 9 meters wide. The manta ray is
most commonly found in the warmer, tropical of waters of the world's
oceans, typically around coral reefs and along the continental shelves where food is in abundance. However, due to their enormous size, manta rays are also commonly spotted hunting out in the open ocean.
The manta ray is a solitary animal and is also a graceful swimmer. Like other large species of fish, manta rays
swim by moving their pectoral fins up and down which propels their
enormous body through the surrounding water. The short tail of the manta
ray also allows the manta ray to be more acrobatic with it's movement,
and they have even be seen leaping out of the water. Manta rays are
known to frequently visit cleaning stations where small fish such as
wrasse and angelfish swim in the manta ray's gills and over it's skin to
feed, in the process cleaning it of parasites
and dead tissue. Manta rays are generally not interested in eating
these smaller fish as they are providing a great service to the manta
ray.
Unlike many sharks, manta rays do not actually have teeth and
instead sieve the food particles out of the water using rows of tiny
plates in their mouths, which they funnel in their mouths as they swim.
Manta rays eat tiny marine organisms including microscopic
plankton, small fish and crustaceans. Despite it's large size, the
relatively docile nature of the manta ray means that it is actually
preyed upon by a number of large marine predators. Large species of
shark such as the great white shark, killer whales and also humans are known to hunt the manta ray.
After mating the female manta ray lays a couple of eggs which actually develop and then hatch inside her. This process is known as aplacental viviparity and is quite commonly seen in the reproduction of a number of shark and ray species. Within 6 weeks of hatching, the female
manta ray gives birth to 1 or 2 manta ray pups, which develop into
large adults fairly quickly. Today, although the manta ray is not
considered to be a species that is in imminent danger of extinction in
the wild, the manta ray population numbers have been declining more
quickly in recent years. Manta rays are particularly susceptible to
pollution in the water and are quickly affected by overfishing in
certain areas, and therefore a lack of food.
