Stingray Injury OverviewStingrays do not actually attack. Injuries from these sharklike creatures are usually defensive actions. Once disturbed, their venomous stinger (spine) near the base of their tails lashes out and can cause punctures or lacerations (cuts). Their mouth parts do not cause injury, but a hickey can occur if they try to suck you. Stingrays are aquatic, cartilaginous vertebrates who are members of the shark family. They have flat bodies and winglike fins. Stingrays are nonassertive and can be found lying in the sand in shallow water at the beach or swimming free in open waters. Most are saltwater creatures, but a few live in fresh water.
