http://en.wikipedia.org/wiki/Spotted_eagle_ray
This ray can be identified by its dark
dorsal surface covered in white spots or rings. Near the base of the ray's relatively long tail, just behind the
pelvic fins, are several
venomous, barbed stingers. Spotted eagle rays commonly feed on small fish and
crustaceans,
and will sometimes dig with their snouts to look for food buried in the
sand of the sea bed. These rays are commonly observed leaping out of
the water, and on at least two occasions have been reported as having
jumped into boats, in one incident resulting in the death of a woman in
the
Florida Keys. The spotted eagle ray is hunted by a wide variety of sharks. The rays are considered
Near Threatened on the
IUCN Red List.
They are fished mainly in Southeast Asia and Africa, the most common
market being in commercial trade and aquariums. They are protected in
the
Great Barrier Reef.
Spotted eagle ray preys mainly upon crabs, crustaceans and also upon hermit crabs,
shrimp, octopi, and some small fish.
The spotted eagle ray's specialized
chevron-shaped tooth structure helps it to crush the mollusks' hard shells.
The jaws of these rays have developed
calcified struts to help them break through the shells of mollusks, by supporting the jaws and preventing dents from hard prey.
These rays have the unique behavior of digging with their snouts in the sand of the ocean. While doing this, a cloud of sand surrounds the ray and sand spews from its gills.
Spotted eagle rays have flat disk-shaped bodies, deep blue or black
with white spots on top with a white underbelly, and distinctive flat
snouts similar to a duck's bill.
Their tails are longer than those of other rays and may have 2–6 venomous spines,
just behind the pelvic fins. The front half of the long and wing-like
pectoral disk has five small gills in its underside.
Mature spotted eagle rays can be up to 5 meters (16 ft) in length;
the largest have a wingspan of up to 3 meters (10 ft) and a mass of 230
kilograms
Steve Irwin, the host of the "Crocodile Hunter" television show was
killed by another type of ray while filming underwater on Australia's
Great Barrier Reef in 2006. He died when a stingray's barb pierced his
heart.
