Among flesh eating animals, the use of venom is a method of subduing prey that cuts across taxonomic boundaries. Generally, venomous animals are small, slow-moving or fragile. The delicate tentacles of a Portuguese man of war, for instance, deliver paralyzing stings. Were it not for this, it would be thrashed to pieces by the struggles of its prey. With a poisonous bite, short sighted spiders prevent insects escaping. Snakes such as vipers or cobras use venom to still fast moving small mammals.
