Cottoidei is a suborder of ray-finned fishes which, according to the 5th edition of Fishes of the World, is placed within the order Scorpaeniformes,{{Inconsistent|reason=Taxobox places it in Perciformes|date=1 April 2025}} alongside the scorpionfishes, flatheads, eelpouts, sticklebacks and related fishes.
Taxonomy
Cottoidei was first proposed as a taxonomic grouping in 1835 by the Swiss-American zoologist Louis Agassiz. The 5th edition of Fishes of the World classifies the Cottoidei as a suborder of the order Scorpaeniformes. Other workers 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 superfamilies of Fishes of the World as infraorders.{{cite journal | author1 = Ricardo Betancur-R | author2 = Edward O.
