The Gasterosteidae are a family of fish including the sticklebacks. FishBase recognises 16 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 classified in the related family Aulorhynchidae.
Sticklebacks are most commonly found in the ocean, but some can be found in fresh water. The freshwater taxa were trapped in Europe, Asia, and North America after the ice age, and have evolved different features from the marine species. Sticklebacks are carnivorous, feeding on small animals such as insects, crustaceans and fish larvae.
Sticklebacks are characterised by the presence of strong and clearly isolated spines in their dorsal fins. Their maximum length is about 4 in, but few of them are more than 3 in long. They mature sexually at a length of about 2 in. All species show a similar mating behaviour, which is also unusual among fish. The males construct a nest from vegetation held together by secretions from their kidneys, then attract females to the nest. The female lays her eggs inside the nest where the male can fertilise them. The male then guards the eggs until they hatch.
