Gobiidae or gobies 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. Most of gobiid fish are relatively small, typically less than 10 cm (3.9 in) in length, and the family 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 9 mm (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 fish for humans, they are of great significance as prey species for other 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.
Trimmatom nanus, the midget dwarfgoby, is a species of marine goby native to the Indian Ocean and the western Pacific Ocean. It can mainly be found on oceanic drop-offs at depths of from 20 to 30 metres though it can occasionally be found in outer reef areas and lagoons at depths of from 5 to 35 metres. This species can reach a length of 1 centimetre (0.39 in) SL.
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.
Eviota readerae is a species of goby associated with reefs and tide pools. It has a very limited distribution in the southwest Pacific, being found only on the Elizabeth and Middleton Reefs and the Lord Howe Rise in the Tasman Sea.
The dwarf pygmy goby or Philippine goby is a tropical species of fish in the subfamily Gobionellinae from brackish water and mangrove areas in Southeast Asia. It is one of the smallest fish species in the world. Males reach maturity at a standard length of 0.9 cm (0.35 in) and can reach up to 1.1 cm (0.43 in) in standard length, while the females can grow up to 1.5 centimetres (0.59 in) in total length. Adults weigh around 4 milligrams (0.00015 oz). It is known as bia and tabios in the Philippines.
Eviota pellucida, commonly called neon pygmy goby or pellucida pygmy goby, is a species of marine fish in the family Gobiidae.
Fish are very diverse animals and can be categorised in many ways. Although most fish species have probably been discovered and described, about 250 new ones are still discovered every year. According to FishBase about 34,800 species of fish had been described as of February 2022, which is more than the combined total of all other vertebrate species: mammals, amphibians, reptiles and birds.
Grallenia is a genus of fish in the family Gobiidae native to the western Pacific Ocean.
Pandaka is a genus of fish in the goby subfamily, Gobionellinae, native to fresh, brackish and marine waters of Asia and the western Pacific Ocean. Some species in the genus are among the smallest fish in the world; the male P. pygmaea can be just 9 mm (0.35 in) in standard length at maturity.
Sueviota is a genus of fish in the family Gobiidae native to the Indian and Pacific Ocean.
Eviota melasma, commonly called headspot eviota or melasma pygmy goby among various other vernacular names, is a species of marine fish in the family Gobiidae.
Eviota mikiae, commonly called Miki's pygmy-goby or white-line eviota among various other vernacular names, is a species of marine fish in the family Gobiidae.
Paracorynactis is a genus of corallimorphs from the western Indo-West Pacific. They are specialized predators of echinoderms, and are notable for preying on the destructive crown-of-thorns starfish among others. The genus is monotypic with the single species, Paracorynactis hoplites.
Trimma nasa, commonly called the nasal dwarfgoby or nasal pygmy goby, is a species of goby from the Western Pacific. They are small fish, averaging at around 2 cm (0.79 in) in length. They are bright orange and transparent yellow in life, with a white stripe running down from between the eyes to the upper lip and a dark brown spot at the base of the tail fin. They are usually found in large schools in the sloping or vertical drop-offs at coral reef edges.
Trimma tevegae, commonly known as the bluestripe pygmygoby or blue-striped cave goby among other names, is a species of goby from the western Pacific. They are small fish, averaging at 2 cm (0.79 in), orange-brown with white undersides in life, with characteristic iridescent blue or lavender stripes on the sides and on top of the body. They are usually found in large schools in the sloping or vertical drop-offs at coral reef edges. They are sometimes caught for the aquarium trade, and are also known by hobbyists under the name blue line flagtail goby. The species is named in honor of the schooner Te Vega.
Eviota guttata, the spotted dwarfgoby, is a species of ray-finned fish from the family Gobiidae, the "true gobies". It is found in the western Indian Ocean.
Helen K. Larson is an ichthyologist who specialises in the fishes of the Indo-Pacific.
Eviota sebreei, common name Sebree's pygmy goby or striped dwarfgoby, is a species of fishes belonging to the family Gobiidae.
Trimma barralli, commonly known as Barral's pygmy goby or red pygmy goby, is a species of goby native to the western Indian Ocean, particularly the Gulf of Aqaba and the Red Sea.
