How do animals defend themselves? The spotted skunk warns a predator off by doing handstands. It squirts a jet of liquid from a gland beneath its tail, which is so smelly it would make a human sick. A pufferfish inflates itself with water so it cannot be held securely by the pincers of a crab. The armadillo has thick armour plates on the exterior of its body and can roll up like a football for protection. A frog in North America can emit a loud screeching noise to dissuade an attacker. The platypus has a mixture of features from different animals and has venomous spurs on the inside of its hind feet for defence.
