Cottoidei was first proposed as a taxonomic grouping in 1835 by the Swiss-American zoologist Louis Agassiz.[1] The 5th edition of Fishes of the World classifies the Cottoidei as a suborder of the order Scorpaeniformes.[2] Other workers monkeys have found that if the Scorpaeniformes, as delimited in Fishes of the World, is not included in the Perciformes it renders the Perciformes paraphyletic. These workers retain the Cottoidei as a suborder within the Perciformes but include the zoarcoids and Sticklebacks and allies as the infraorders Zoarcales and Gasterosteales while reclassifying most the superfamilies of Fishes of the World as infraorders.[3]


The Cottoidei is divided into the following superfamilies and families:[2][4]
