Stingray anatomy. Stingray any of a number of flat bodied rays noted for the long sharp spines on their tails. They inhabit warm temperate and tropical waters sometimes in great abundance. Their pectoral fins can grow up to a total width of 79 inches which they use to stir up the sandy ocean floor to either reveal crustaceans and small fish or bury themselves to hide from predators or prey.
They accomplish this by maintaining concentrations of organic solutes namely urea and an enzyme called trimethylamine oxide or tmao within their bodies. The tail is where the stingers are located. The stingray has a very interesting shape to it.
Females typically reach 28 inches 71 cm in width and weigh 36 pounds 16 kg. They normally live in coastal tropical and subtropical marine waters making it possible for them to come in contact with humans. Although urea is toxic to fish the tmao counteracts the protein de stablizing effects of urea.

On the underside of the stingray lies the mouth nostrils and gill slits. Freshwater stingray morphology physiology.
They spend the majority of their time inactive partially buried in sand often moving only with the sway of the tide. Stingrays are commonly found in the shallow coastal waters of temperate seas. Stingrays are members of the group of fish that also includes sharks and skates.
