A group of stingrays is called a fever. Stingrays normally travel in groups to hunt but are also known to travel individually and in pairs.
Stingrays belong to the superorder Batoidea, which also includes sawfish, skates and electric rays. While it is very different in nature, the closest relative of the batoid is the shark.
One of the most distinctive features of the stingray is its often scary-looking barbed, whip-like tail. Despite their menacing appearance, however, stingrays are docile creatures that only sting to defend themselves.To help prevent getting stung, swimmers should avoid stepping on stingrays by always shuffling their feet when entering shallow water.
