Blennioidei

a suborder of fishes of the order Perciformes. Body length, usually 10–50 cm. The pelvic fins of most species are located on the throat and have a spine and no more than four soft rays; in some species pelvic fins are absent. They are littoral, bottom-dwelling fishes; many populate the tidal zone of the littoral, hiding during low tide under rocks, among algae, and in depressions filled with water. There are two superfamilies, comprising 20 families. The superfamily Stichaeoidae includes the families Lumpenidae, Pholidae, Anarrhichadidae, and Stichaeidae; the superfamily Blennioidae includes the families Tripterygiidae, Blenniidae, and Clinidae. The fishes can crawl onto dry land, moving themselves by jumping with their fins.
