Microdesmus is a genus of wormfishes native to the Atlantic Ocean and the eastern Pacific Ocean. [1]
There are currently 16 recognized species in this genus: [1]
Eleotridae is a family of fish commonly known as sleeper gobies, with about 34 genera and 180 species. Most species are found in the tropical Indo-Pacific region, but there are also species in subtropical and temperate regions, warmer parts of the Americas and near the Atlantic coast in Africa. While many eleotrids pass through a planktonic stage in the sea and some spend their entire lives in the sea; as adults, the majority live in freshwater streams and brackish water. One of its genera, Caecieleotris, is troglobitic. They are especially important as predators in the freshwater stream ecosystems on oceanic islands such as New Zealand and Hawaii that otherwise lack the predatory fish families typical of nearby continents, such as catfish. Anatomically, they are similar to the gobies (Gobiidae), though unlike the majority of gobies, they do not have a pelvic sucker.
Cathorops is a genus of catfishes in the family Ariidae found in the Atlantic and Pacific Oceans. These species are found in the eastern and western Central and South America in brackish and freshwater habitats. This genus is a strongly supported clade of this family. It consists of a natural group in which the monophyly is well-defined by morphological and molecular evidence and the genus probably includes several unrecognized species from both American coasts.
Silhouettea is a genus of gobies native to the Indian Ocean and the western Pacific Ocean. The name of this genus refers to the island of Silhouette in the Seychelles where the type specimens of the type species, Silhouettea insinuans, were collected.
Symphurus is a genus of fish in the family Cynoglossidae found in the Atlantic, Indian and Pacific Ocean. Most species mainly occur in relatively shallow water, including estuaries. Some species are also found in deeper water, including S. thermophilus that lives at hydrothermal vents. These species are distinguished by merged dorsal, caudal and anal fins, the absence of a lateral line and pectoral fins, and the presence of only one pelvic fin. They are sinistral flatfishes, meaning that as adults, their crania are asymmetrical, with both eyes on the left side. The largest species grows to about 32 cm (1 ft) long.
Hypsoblennius is a genus of combtooth blennies found in the Pacific and Atlantic Oceans.
Stathmonotus is a genus of chaenopsid blennies found in the Pacific and Atlantic oceans.
Anchoa is a genus of ray-finned fishes in the family Engraulidae. It currently consists of 35 species.
Halicampus is a genus of pipefishes of the family Syngnathidae, containing 12 described species.
Trinectes is a genus of American soles native to the Americas. Most species are coastal, occurring in both salt and brackish water, but several may enter fresh water and one, T. hubbsbollinger, is restricted to rivers. They are fairly small, with the largest species only reaching 25 cm (9.8 in) in length.
Etropus is a genus of large-tooth flounders native to the coastal waters of the Americas.
Ctenogobius is a genus of gobies with a wide distribution in fresh, brackish and marine waters.
Evorthodus is a genus of gobies native to the Atlantic coast from Chesapeake Bay, United States, to northern South America and along the Pacific coast of Panama and Ecuador.
Gobionellus is a genus of gobies native to fresh, marine and brackish waters along the Atlantic and Pacific coasts of the Americas.
Gobiosoma is a genus of gobies native to fresh, brackish and marine waters of the Americas.
Lythrypnus is a genus of gobies native to the Atlantic and Pacific coasts of the Americas including Cocos Island and the Galapagos Islands.
Microgobius is a genus of gobies native to the Pacific and Atlantic coasts of the Americas.
Cerdale is a genus of wormfishes native to the western Atlantic Ocean and the eastern Pacific Ocean.
Gunnellichthys is a genus of wormfishes native to the Indian Ocean to the central Pacific Ocean.
Paragunnellichthys is a genus of wormfishes native to the Indian Ocean and the western Pacific Ocean.
Ptereleotris is a genus of dartfishes found in the Atlantic, Indian and Pacific oceans.
