Scopaeocharax is a genus of characins endemic to Peru, where both species are found in the upper and middle Huallaga River basin. [1]
There are currently 2 recognized species in this genus: [1]
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.
Saccopharynx is a genus of deep-sea eels with large mouths, distensible stomachs and long, scaleless bodies. Commonly, these fish are called gulpers or gulper eels. It is the only genus in the family Saccopharyngidae, and is part of the derived lineage of the "saccopharyngiforms," which includes other mid-water eel species. The name is from Latin saccus meaning "sack" and Greek φάρυγξ, pharynx.
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.
Enchelycore is a genus of moray eels in the family Muraenidae. Enchelycore species are generally small to medium-sized eels, most ranging from 2 to 3 feet in length, with the largest being the Mosaic Moray, which reaches a length of 6 feet (180 cm). Members of the genus feature distinctive, curved jaws that prevent them from fully closing their mouth and aids them in catching, and holding on to prey. Enchelycore species can also feature extremely bright colors and ornate markings.
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.
Boehlkea is a genus of small characins found in the Amazon basin in South America.
Ichthyococcus are a genus of lightfishes. It is one of seven genera in the family Phosichthyidae.
Chaenopsis is a genus of pikeblennies found in the Pacific and Atlantic oceans.
Lucayablennius zingaro, the arrow blenny, is a species of chaenopsid blenny found in coral reefs around the Bahamas and the Caribbean, in the western central Atlantic ocean. It can reach a maximum length of 3.8 centimetres (1.5 in) TL. This species is the only known member of its genus. They are red to reddish brown in color with white stripes that fade to yellow towards the tail. The tail is always held at a curve or bend and typically has three black spots on the dorsal side. Unlike most blennys, the arrow blenny does not perch its self on rocks or coral. Rather, it waits floating in the water column before swooping down to catch unsuspecting zooplankton.
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.
Nettenchelys is a genus of eels in the duckbill eel family Nettastomatidae.
Apterichtus is a genus of fish in the family Ophichthidae. Many of its species are called finless eels.
Gordiichthys is a genus of eels in the snake eel family Ophichthidae. It currently contains the following species:
Myrophis is a genus of eels in the snake eel family Ophichthidae.
Ophichthus is a genus of eels in the snake eel family Ophichthidae.
Brachychalcinus is a genus of characins found in tropical South America, with five currently described species:
Chrysobrycon is a genus of characins endemic to South America.
Coryphopterus is a genus of gobies primarily found in the western Atlantic Ocean, although some species are found in the Indian and/or Pacific oceans.
Oxyurichthys is a genus of fish in the subfamily Gobionellinae, commonly known as arrowfin gobies. They are distributed in the tropical and subtropical Indian and Pacific Oceans; one species is also known from the western Atlantic Ocean. Most species live in shallow waters under 10 meters deep over fine substrates such as silt.
The dottedline snake eel is a species of eels in the family Ophichthidae. It was described by John E. McCosker and Eugenia Brandt Böhlke in 1984. It is a marine, temperate water-dwelling eel which is known from the western central Atlantic Ocean. It is known to dwell at a depth of 183 meters.
