Blenny (from the Greek ἡ βλέννα and τό βλέννος, mucus, slime) is a common name for a type of fish. The term is ambiguous, having been applied to several families of percomorph marine, brackish, and some freshwater fish sharing similar morphology and behaviour. Six families are considered "true blennies", all grouped together under the order Blenniiformes its members are referred to as blenniiformids. About 151 genera and nearly 900 species have been described within the order. The order was formerly classified as a suborder of the Perciformes but the 5th Edition of Fishes of the World divided the Perciformes into a number of new orders and the Blenniiformes were placed in the percomorph clade Ovalentaria alongside the such taxa as Cichliformes, Mugiliformes and Gobiesociformes. Blenniformids are generally small fish, with elongated bodies (some almost eel-like), and relatively large eyes and mouths. Their dorsal fins are often continuous and long the pelvic fins typically have a single embedded spine and are short and slender, situated before the pectoral fins. The tail fin is rounded. The blunt heads of blenniiformids often possess elaborate whisker-like structures called cirri. As generally benthic fish, blenniiformids spend much of their time on or near the sea floor many are reclusive and may burrow in sandy substrates or inhabit crevices in reefs, the lower stretches of rivers, or even empty mollusc shells. True blennies are widely distributed in coastal waters,... Learn more about Blenny
