[5] As of 2013, 45 species have been listed as vulnerable or endangered by the IUCN. The status of some other species is poorly known, leading to their being listed as data deficient.

Research indicates that when humans do become the object of a shark attack, it is possible that the shark has mistaken the human for species that are its normal prey, such as seals. [ 111 ] [ 112 ] This was further proven in a recent study conducted by researchers at the California State University's Shark Lab.
In order to sting their victims, they jerk their tails as the stinger falls off and stays in the wound that they have created. The stinger of a whiptail stingray is pointy, sharp with jagged edges. They range in size from 0.18 to 2.0 m (0.59 to 6.56 ft) or more across in the case of the smalleye stingray and giant freshwater stingray.
This species is a solid gray, brown, reddish, or olive-green above, and whitish below with dark fin margins. Young rays may have white spots. [13] [15] The largest recorded common stingray specimen was found in 2016 in the İzmir Province of Turkey in the course of a study on trolling. Its fins had a width of 2.21 metres (7.3 ft), although its ...
