The Gasterosteidae are a family of fish including the sticklebacks. FishBase currently recognises sixteen species in the family, grouped in five genera. However several of the species have a number of recognised subspecies, and the taxonomy of the family is thought to be in need of revision. Although some authorities give the common name of the family as "sticklebacks and tube-snouts", the tube-snouts are currently classified in the related family Aulorhynchidae.An unusual feature of sticklebacks is that they have no scales, although some species have bony armour plates. They are related to pipefish and seahorses.Stickleback are most commonly found in the ocean, but can be found in some freshwater lakes. The freshwater species were trapped in freshwater lakes in Europe, Asia and North America after the ice age, and have evolved different features from the ocean variety. They feed on small crustaceans and fish larvae.
