Stingrays .derive their name from their slender, whip-like tails equipped with venomous spines. Stingrays are neither threatened nor endangered species. They've been hunted for centuries for their meat and also today stingrays are marketed for food in various countries around the world, principally in Europe and Asia.
Behavior of stingrays
They live in the bottom parts of shallow tropical waters. Looking carefully, you are likely to find them lying on a seabed, buried or partially covered with sand. They can move very rapidly when threatened or in pursuit of a passing fish. They also eat mollusks and crustaceans, crushing then with their flat, strong teeth.
Most of stingrays are not especially afraid of humans. When approached, they swim gently to another place naturally avoiding too close contact. In many places around the world they became tourist attraction, where people can swim together or even feed them.
General characteristics of stingrays
Stingrays can be found in the major oceans; Atlantic, Indian and Pacific Oceans. Most stingrays are marine, living in salt water but they can be found in freshwater and where salt and fresh water mix (brackish water). The shape as can be seen in the pictures, the side of the head has a continuous shape with the outer side margin of the pectoral fin, the fins that look like wings.
They breath by drawing water through a small hole behind the eye and expel the water through gill slits on the underside of the disc. The dorsal fin or backward fin, does not exist or sometimes are hard to distinguish. The disc is about 1.2 times as broad as the length.
The stingray does not have a tail fin (cuadal fin). Instead it has a tail and it looks like a whip with a long venomous spine on the tail. The spine is replaced every four months. Most species have at least 1 long venomous spine on the tail, and some stingrays that are seen to have two.
Injuries to humans from stingrays occur when an unsuspecting person steps on a ray, causing the creature to reflexively strike out with its tail. The stinger apparatus then injects a toxin, causing immediate shooting pain. Although there is no known antidote for their toxin, it's rarely fatal for humans.
The largest of these is the specie is Trygonidae with a total length of about 4 meters. With the above calculations, the total width can be approximately 4.8 meters.
