Are the barbs on a stingray poisonous?
Stingrays have long, thin, whip-like tails equipped with one to three barbed venomous spinal blades. Although they are generally shy, they may strike when unintentionally stepped on. Their venom causes intense pain, but the main risk of a stingray injury is the puncture wound.

Once the stingray is in motion, its tail becomes a whiplike weapon with a poisonous nail sticking out of it.
