Aulorhynchidae

Aulorhynchidae, the tube-snouts, is a small family of marine ray-finned fishes belonging to the suborder Gasterosteoidei in the order Perciformes. These fishes are found in the northern Pacific Ocean.

==Taxonomy== Aulorhynchidae was first proposed as a family in 1861 by the American zoologist Theodore Gill, when he described Aulorhynchus flavidus, placing it in a new monotypic family. This family is included in the suborder Gasterosteoidei of the order Scorpaeniformes in the 5th edition of Fishes of the World. Other authorities treat the Gasterosteoidei as the infraorder Gasterosteales within the suborder Cottoidei or as a sister clade to the Zoarcales in the order Zoarciformes. Some authorities include the genus Aulichthys in the Hypoptychidae, but the 5th edition of Fishes of the World puts this taxon in the family Aulorhynchidae.
