The
spotted eagle ray is a cartilaginous fish of the eagle ray family,
Myliobatidae. Binomial name of Spotted Eagle Ray is Aetobatus narinari. It can
be found globally in tropical regions, including the Gulf of Mexico, Hawaii , off the coast of West Africa, the Indian Ocean,
Oceania, and on both coasts of the Americas at depths down to about 80
meters (262 ft). Spotted eagle rays are beautiful creatures with distinct
markings that differ from other rays.
The
main body is roughly a diamond-shaped disk, with spots covering the dorsal
surface in varying colors of white, yellow and green (McClane, 1978). The ventral surface is white and the tail is
black, which sometimes can be twice the length of the disk. The body is normally thicker than other rays.
The spotted eagle ray possesses only one series of teeth in each jaw which are
relatively broad and flat in nature.
Spotted
eagle rays are elegant and graceful swimmers. The rays are most commonly seen
alone, but occasionally swim in groups. A schooling species, several spotted
eagle rays will group together to form a large school when swimming in the open
water column, where they will travel great distances together. Rays are
ovoviviparous, the female retaining the eggs then releasing the young as
miniature versions of the parent.
Spotted
eagle rays are predators, and the majority of their diet consists of
gastropods, mollusks and crabs (Schluessel et al., 2010). They also eat shrimp, octopus, worms and
small fish (MarineBio).
