Pascua is a genus of gobies native to the Pacific Ocean. [1] The origin of the name "Pascua" is from the Spanish for "Easter" in recognition of the Easter Island range of the type specimen. [2]
There are currently two recognized species in this genus: [1]
A third species in this genus Pascua readeri (Hoese & Larson, 2005) has been recognised by some authorities, [3] but is placed in Hetereleotris by FishBase. [4]
Gobiidae is a family of bony fish in the order Gobiiformes, one of the largest fish families comprising more than 2,000 species in more than 200 genera, sometimes referred to as the "true gobies". Most of them are relatively small, typically less than 10 cm (3.9 in) in length. The Gobiidae includes some of the smallest vertebrates in the world, such as Trimmatom nanus and Pandaka pygmaea, Trimmatom nanus are under 1 cm long when fully grown, then Pandaka pygmaea standard length are 9mm (0.35 in),maximum known standard length are 11 mm (0.43 in). Some large gobies can reach over 30 cm (0.98 ft) in length, but that is exceptional. Generally, they are benthic, or bottom-dwellers. Although few are important as food for humans, they are of great significance as prey species for commercially important fish such as cod, haddock, sea bass, and flatfish. Several gobiids are also of interest as aquarium fish, such as the dartfish of the genus Ptereleotris. Phylogenetic relationships of gobiids have been studied using molecular data.
Fusigobius is a genus of coral reef inhabiting gobies found throughout the Indian and western Pacific Oceans.
Pascua caudilinea, the Pascua goby, is a species of goby endemic to the waters around Easter Island. It has only been recorded from tide pools down to a depth of 40 metres (130 ft). This species can reach a length of 2.8 centimetres (1.1 in) SL.
Valenciennea is a genus of small, bottom-dwelling fish in the family Gobiidae. They are found over sandy bottoms, often at coral reefs in the Indo-Pacific. The members of the genus tend to rest directly on the substrate for extended periods of time. While this is a common behavior for members of the family, this genus also float motionless directly above the substrate, which is why they are sometimes called glider gobies. Their resting behavior has resulted in the vernacular name "sleeper gobies", which invites confusion with the related family Eleotridae. The members of this genus are known to be carnivorous sand-sifters; to eat, they simply engulf entire mouthfuls of sand which they expel through their gills. Specialized structures in their gills filter small crustaceans and worms as the sand is expelled. It is this specific trait that makes some members of the genus attractive to the marine aquarist, and they are often introduced into a marine aquarium for sand-sifting. Some of the species are known to be monogamous. The genus was named after notable French zoologist Achille Valenciennes. These fish are difficult to keep in a tank. Tanks with plenty of live sand and live rock are recommended. Offer foods such as sinking shrimp pellets. Fish may die even if eating properly.
Eviota is a genus of fish in the family Gobiidae, commonly as dwarfgobies found in the Indo-Pacific region, where it is distributed from Japan to Australia and from Africa to Pitcairn Island. Species are mainly associated with coral reefs. Many of these fish are short-lived, with life cycles as brief as 3.5 weeks in the tropics. Some species are hermaphrodites and some representatives live symbiotically among the tentacles of the mushroom coral.
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.
Tomiyamichthys is a genus of gobies found from the Red Sea through the Indian Ocean to the western Pacific Ocean. The name of this genus honours the Japanese ichthyologist Itiro Tomiyama of the Tokyo Imperial University, who described the type species, Tomiyamichthys oni, in 1936.
Bryaninops is a tropical Indo-Pacific genus of gobies. The genus takes its common name from the fact that it is commensal on gorgonians and black coral. The genus is further characterised by cryptic colouration.
Egglestonichthys is a genus of gobies native to brackish and marine waters of the Indian Ocean and the western Pacific Ocean.
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.
Hetereleotris is a genus of gobies native to the western Indian Ocean and the western Pacific Ocean.
Nesogobius is a genus of goby native to the coastal waters of Australia.
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.
Stonogobiops is a genus of gobies native to the Indian and Pacific oceans. This is one of the "shrimp goby" genera, the members of these genera being commensal with various species of shrimps.
Sueviota is a genus of fish in the family Gobiidae native to the Indian and Pacific Ocean.
Tryssogobius is a genus of small gobies native to the western Pacific Ocean. The species in this genus are known colloquially as "fairygobies".
Ptereleotris is a genus of dartfishes found in the Atlantic, Indian and Pacific oceans.
Istigobius ornatus, the Ornate goby, is a species of gobies found in the Indo-Pacific.
Thalasseleotris is a genus of gobies comprising two species in the family Thalasseleotrididae from the south-western Pacific Ocean in the seas off Australia and New Zealand. The generic name is derived from the Greek Thalassa meaning "sea" and the generic name Eleotris as at the time it was named the genus was considered to be in the family Eleotridae.
