Subfamilies & genera

Subfamily Ptereleotrinae

Subfamily Microdesminae

The Microdesmidae, the wormfishes and dartfishes, were a family of goby-like fishes in the order Gobiiformes, more recent workers have placed this taxon within the Gobiidae, although the researchers do not define the taxonomic status of this grouping within that family. [2] Two subfamilies in this family were briefly treated as full families - the Ptereleotrinae (dartfishes) and Microdesminae (wormfishes). [3] The family includes about 82 species.

They are found in shallow tropical waters, both marine and brackish, often burrowing in estuarine mud. They are small fish, the largest species reaching only about 12 cm in length.

A flatfish is a member of the ray-finned demersal fish order Pleuronectiformes, also called the Heterosomata, sometimes classified as a suborder of Perciformes. In many species, both eyes lie on one side of the head, one or the other migrating through or around the head during development. Some species face their left sides upward, some face their right sides upward, and others face either side upward.

<span class="mw-page-title-main">Characidae</span> Family of fishes

Characidae, the characids or characins, is a family of freshwater subtropical and tropical fish belonging to the order Characiformes. The name "characins" is an historical one, but scientists today tend to prefer "characids" to reflect their status as a, by and large, monophyletic group. To arrive there, this family has undergone much systematic and taxonomic change. Among those fishes remaining in the Characidae currently are the tetras, comprising the very similar genera Hemigrammus and Hyphessobrycon, as well as a few related forms, such as the cave and neon tetras. Fish of this family are important as food in several regions, and also constitute a large percentage of captive freshwater aquarium fish species.

<span class="mw-page-title-main">Gobiidae</span> Family of fishes

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.

<span class="mw-page-title-main">Dartfish</span> Subfamily of fishes

Dartfishes are a group of fish, formerly considered to be a subfamily, Ptereleotrinae, of goby-like fishes in the family Microdesmidae of the order Gobiiformes, Authorities now consider the species in the family Microdesmidae are within the Gobiidae, although the researchers do not define the taxonomic status of this grouping within that family. They are saltwater fish.

<span class="mw-page-title-main">Gobiiformes</span> Order of fishes

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".

Springeratus caledonicus, the Caledonian weedfish, is a species of clinid found around New Caledonia and Australia. This species placement in the family Clinidae has been questioned with some feeling that it is best placed in the family Microdesmidae.

<i>Ptereleotris randalli</i> Species of fish

Ptereleotris randalli, the Brazilian dartfish, is a fish belonging to the family Gobiidae and subfamily Ptereleotrinae. Like other dartfishes, it lives over sand and rubble bottoms, and quickly retreats into holes when approached. It was originally thought to be restricted to Brazil, south to Santa Catarina, but recently reported for the southern Caribbean, where it's found at depths of 8-60m.
