Their stinger is a razor-sharp, venomous spine which grows from the ray's whip-like tail. Stingrays are flat so they can hide on the seabed.
When attacked by predators or stepped on, the stingray's barbed stinger is whipped up. However, fatal stings, such as that which killed Australian naturalist and TV personality Steve Irwin in September 2006, are extremely rare.
