Blenny is a common name for many types of fish, including several families of percomorph marine, brackish, and some freshwater fish sharing similar morphology and behaviour. Six families are considered "true blennies", grouped 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.
Ophichthidae is a family of fish in the order Anguilliformes, commonly known as the snake eels. The term "Ophichthidae" comes from Greek ophis ("serpent") and ichthys ("fish"). Snake eels are also burrowing eels. They are named for their physical appearance, as they have long, cylindrical, snake-like bodies. This family is found worldwide in tropical to warm temperate waters. They inhabit a wide range of habitats, from coastal shallows and even rivers, to depths below 800 m (2,600 ft). Most species are bottom dwellers, hiding in mud or sand to capture their prey of crustaceans and small fish, but some are pelagic.
Gymnothorax is a genus of fish in the family Muraenidae found in Atlantic, Indian and Pacific Ocean. With more than 120 species, it the most speciose genus of moray eels.
Apogon is a large genus of fish in the family Apogonidae, the cardinalfishes. They are among the most common fish on coral reefs. Over 200 species have been classified in genus Apogon as members of several subgenera. Some of these subgenera, such as Ostorhinchus, have been elevated to genus status, leaving just over 50 species in the genus.
Coralliozetus is a genus of chaenopsid blennies mostly found in the eastern Pacific Ocean with one species (C. cardonae) occurring in the western Atlantic Ocean. Additionally, one species (C. clausus) is endemic to Cocos Island, Costa Rica.
Elacatinus is a genus of small marine gobies, often known collectively as the neon gobies. Although only one species, E. oceanops, is technically the "neon goby," because of their similar appearance, other members of the genus are generally labeled neon gobies, as well. Except for a single East Pacific species, all reside in warmer parts of the West Atlantic, including the Caribbean and Gulf of Mexico. They are known for engaging in symbiosis with other marine creatures by providing them cleaning service that consists of getting rid of ectoparasites on their bodies. In return, Elacatinus species obtain their primary source of food, ectoparasites.
Pareques acuminatus, commonly known as the high-hat, donkeyfish, cubbyu, Steindachner's ribbonfish, streaked ribbonfish, striped ribbonfish or striped drum, is a species of marine ray-finned fish belonging to the genus Pareques in the family Sciaenidae, the drums and croakers. This species is found in the western Atlantic Ocean.
In the 10th edition of Systema Naturae, Carl Linnaeus described the Pisces as:
Always inhabiting the waters; are swift in their motion and voracious in their appetites. They breathe by means of gills, which are generally united by a bony arch; swim by means of radiate fins, and are mostly covered over with cartilaginous scales. Besides the parts they have in common with other animals, they are furnished with a nictitant membrane, and most of them with a swim-bladder, by the contraction or dilatation of which, they can raise or sink themselves in their element at pleasure.
Peprilus is a genus of fish in the family Stromateidae found in Pacific and Atlantic Oceans.
Starksia is a genus of labrisomid blennies native to the western Atlantic Ocean and the eastern Pacific Ocean. Their typical length is 2 cm (0.79 in) SL. The generic name honours the American ichthyologist Edwin Chapin Starks (1867-1932) of Stanford University for his work on Pacific coastal fishes. As a genus Starksia is distinguished from other labrisomids by their scaled bodies, two obvious soft rays in the pelvic fin and the male's have an intromittent organ which is near to or attached to the first spine of their anal fins, which is also somewhat separated from the fin.
Myrophis is a genus of eels in the snake eel family Ophichthidae.
Ophichthus is a genus of eels in the snake eel family Ophichthidae.
Dysomma is a genus of eels in the cutthroat eel family Synaphobranchidae.
Brotula is a genus of cusk-eels. It is the only genus is the subfamily Brotulinae.
Lepophidium is a genus of cusk-eels.
Otophidium is a genus of cusk-eels, part of the subfamily Ophidiinae in the family Ophidiidae. They are found in the western Atlantic and eastern Pacific.
The band cusk-eel is a fish species in the family Ophidiidae. Widespread in the Western Atlantic from North Carolina, United States, and northern Gulf of Mexico to southeastern Brazil. Absent from The Bahamas. Marine reef-associated tropical demersal fish, up to 30 cm (12 in) long.
Bairdiella is a genus of marine ray-finned fishes belonging to the family Sciaenidae, the drums and croakers. These fishes are found in the western Atlantic and eastern Pacific Ocean.
Ophidiinae is a subfamily of the cusk eel family Ophidiidae. The species in the subfamily are characterised by having their pelvic fins situated far forward on the body and supported by a forward orientated extension of the pelvic girdle, they lack barbels on the mouth and chin and they are covered in small cycloid scales arranged in horizontal or diagonal rows. Some species have a modified swim bladder and the anterior vertebrae which enables them to generate sounds. and some of these modifications are sexually dimorphic and make the fish capable of generating sound. They have two rays in each ventral fin and the caudal fin has 9 rays. Most species are benthic and occur on the continental shelf.
Ophidion zavalai is a species of cusk-eel from the Ophidiidae family. It was discovered through taxonomic revisions of the band cusk-eel (Ophidion holbrookii) on the coast of Laje da Conceição Island, where its type locality is given. It occurs on soft bottoms off the eastern to southeastern coast of Brazil.
