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.
Stiphodon is a genus of freshwater gobies. They inhabit swift, clear streams close to the sea and are found in large parts of Asia and Oceania. Many of the 36 currently recognized species have extremely restricted distributions on single islands or even single streams. These are small gobies with bodies squarish in cross section. A female of Stiphodon multisquamus with a standard length of 60.4mm is the largest Stiphodon individual on record.
Schismatogobius is a genus of fish in the subfamily Gobionellinae. They are native to southern and eastern Asia, Australia and the Pacific Islands. Adults dwell in freshwater habitat such as streams and rivers, where they live along the sand and gravel substrates.
Lentipes is a genus of gobies native to fresh, marine and brackish waters of the Malay Archipelago and islands in the Pacific. Its species are typically from fast-flowing streams and some are anadromous.
Mugilogobius is a genus of fish in the family Gobiidae. They are found in fresh, brackish and marine water of the Indo-Pacific region. Several of the freshwater species have highly restricted distributions.
Redigobius is a genus of fish in the goby family, Gobiidae, known commonly as dualspot gobies. They are native to the western Indo-Pacific region, where they occur in estuaries and freshwater habitats just above the tidal influence.
Stenogobius is a genus of fish in the goby subfamily, Gobionellinae. They are native to fresh, brackish and marine waters along the coasts of the Indian and Pacific Oceans. They are known commonly as coastal stream gobies.
The Gobiiformes are an order of fish that includes the gobies and their relatives. The order, which was previously considered a suborder of Perciformes, is made up of about 2,211 species that are divided between seven families. Phylogenetic relationships of the Gobiiformes have been elucidated using molecular data. Gobiiforms are primarily small species that live in marine water, but roughly 10% of these species inhabit fresh water. This order is composed chiefly of benthic or burrowing species; like many other benthic fishes, most gobiiforms do not have a gas bladder or any other means of controlling their buoyancy in water, so they must spend most of their time on or near the bottom. Gobiiformes means "goby-like".
The Gobionellinae are a subfamily of fish which was formerly classified in the family Gobiidae, the gobies, but the 5th Edition of Fishes of the World classifies the subfamily as part of the family Oxudercidae. Members of Gobionellinae mostly inhabit estuarine and freshwater habitats; the main exception is the genus Gnatholepis, which live with corals in marine environments. The subfamily is distributed in tropical and temperate regions around the world with the exception of the northeastern Atlantic Ocean, the Mediterranean Sea, and the Ponto-Caspian region. It includes around 370 species and 55 genera: Wikipedia articles about genera list about 389 species.
Caecogobius cryptophthalmus is a species of goby that is endemic to underground habitats in Calbiga on the Philippine island of Samar. This species is one of two members of the genus Caecogobius, which are the only known cavefish in the Philippines. Like other cavefish, C. cryptophthalmus has reduced eyes and pigmentation.
Eugnathogobius illotus is a species of goby native to marine, brackish and fresh waters of Singapore, Thailand, Brunei and the Philippines.
Eugnathogobius is a genus of gobies native to fresh, brackish and marine waters of the Indian Ocean and the western Pacific Ocean region.
Gnatholepis is a genus of fish in the family Gobiidae, the gobies. It is the only marine genus in the subfamily Gobionellinae, which otherwise includes mostly estuary-dwelling and freshwater fish. Gnatholepis are tropical fish associated with sandy habitat around corals.
Paedogobius kimurai is a species of goby from the subfamily Gobionellinae, and the only member of the monotypic genus Paedogobius. It is native to marine and brackish waters of inner bays in Japan, Thailand and Australia. Its English language common names include wide-gape paedomorphic goby and babyface goby. Its Japanese language common name is shirasukiba-haze.
Stigmatogobius is a genus of fish in the goby subfamily, Gobionellinae. It is distributed in the Indo-Pacific region, specifically the Indo-Malayan zone. Species can be found along the substrate or hiding in plant litter in freshwater habitat, and sometimes in estuary habitat, such as mangrove stands.
Eugnathogobius siamensis is a species of goby.
Pseudogobiopsis lumbantobing is a species of goby from the subfamily Gobionellinae which is found in Java and Sumatra where it occurs in freshwater rivers and streams at altitudes of 5–22 metres (16–72 ft), with substrates made up of sand, gravel, rock, and boulders and where there may be growths of algae and aquatic macrophytes. This species has been traded in the European aquarium trade since 2001.

Oxyurichthys auchenolepis, commonly known as the scaly-nape tentacle goby, is a species of goby found in the western central Pacific. This species reaches a length of 13 cm (5.1 in).
