Leiognathus is a genus of marine ray-finned fishes, ponyfishes from the family Leiognathidae. They are native to the Indian Ocean and the western Pacific Ocean. [2] They are sometimes known as silverbellies. [3]
There are currently 7 recognized species in this genus: [2]
Acanthurus is a genus of marine ray-finned fish belonging to the family Acanthuridae, which includes the surgeionfishes, unicornfishes and tangs, found in the Atlantic, Indian and Pacific Ocean. They are found in tropical oceans, especially near coral reefs, with most species in the Indo-Pacific but a few are found in the Atlantic Ocean. As other members of the family, they have a pair of spines, one on either side of the base of the tail which are dangerously sharp.
Leiognathidae, the ponyfishes, slipmouths or slimys / slimies, are a small family of fishes in the order Perciformes. They inhabit marine and brackish waters in the Indian and West Pacific Oceans. They can be used in the preparation of bagoong.
Secutor is a genus of ponyfishes native to the Indian Ocean and the western Pacific Ocean.
The striped ponyfish is a species of marine ray-finned fish, a ponyfish from the family Leiognathidae. It is native to the Indian Ocean and the western Pacific Ocean, from the Red Sea and the eastern coast of Africa to Fiji and Samoa, where it occurs in coastal marine and brackish waters. It occurs at depths of from 20 to 50 metres. It is a predator upon smaller fishes, small crustaceans and polychaete worms. This species grows to a length of 21 centimetres (8.3 in) TL though most do not exceed 17 centimetres (6.7 in) TL. It is of minor importance to local commercial fisheries. This species is the only known member of its genus.
Equulites is a genus of ponyfishes native to the Indian Ocean and the western Pacific Ocean. Analysis of mitochondrial DNA published in 2017 has suggested that Equulites elongates is in fact a species group made up of three species Equulites aethopos, Equulites elongates and Equulites popei.
Eubleekeria is a genus of marine ray-finned fishes, ponyfishes from the family Leiognathidae which are native to the Indian Ocean and the western Pacific Ocean.
Gazza is a genus of marine ray-finned fishes, ponyfishes from the family Leiognathidae which are native to the Indian Ocean and the western Pacific Ocean.
Karalla is a genus of marine ray-finned fishes, ponyfishes from the family Leiognathidae which are native to the Indian Ocean and the western Pacific Ocean.
Nuchequula is a genus of ponyfishes native to the Indian Ocean and the western Pacific Ocean.
Photopectoralis is a genus of marine ray-finned fishes, ponyfish from the family Leiognathidae. They are native to the Indian Ocean and the western Pacific Ocean.
Eubleekeria splendens, common names splendid ponyfish and blacktip ponyfish, is a species of ponyfish.
Leiognathus longispinis, commonly known as the longspine- or Smithurst's ponyfish, is a fish of brackish and marine waters found in the Indian and western Pacific Oceans, from India through Malaysia and Indonesia south to northern Australia and east to the Philippines and Fiji It was described in 1835 by French Zoologist Achille Valenciennes from a specimen caught off Waigeo island in Irian Jaya in New Guinea. In 1886 Ramsay and Ogilby described what turned out to the same species from Hood Lagoon in Papua New Guinea, naming it Leiognathus smithursti. In 2008, ichthyologists Prosanta Chakrabarty and John S. Sparks resurrected the genus Aurigequula and placed L. longispinis and L. fasciatus in it, on the basis of a horizontal row of yellow markings on their flanks and elongated second spine of the dorsal fin. However, a molecular study showed that the genus Leiognathus was nested within Aurigequula, and hence the genera were merged once more. Fishbase places this species in Leiognathus while retaining the striped ponyfish in the monotypic Aurigequula.
Leiognathus equulus, the common ponyfish is a species of marine ray-finned fish, a ponyfish from the family Leiognathidae. It occurs in brackish and marine waters from East Africa to Fiji in the Indian and western Pacific Oceans, Red Sea and Persian Gulf.
Eubleekeria jonesi, commonly known as Jones’s pony fish, is a marine rat-finned fish, a ponyfish from the family Leiognathidae. It is native to the Indian Ocean. This species was first formally described as Leiognathus jonesi in 1971 by the Indian ichthyologist P.S.B.R. James (1934-2019) and its specific name honours James’ predecessor as director of the Indian Central Marine Fisheries Institute in Kochi, Santhappan Jones (1910-1997).
Photolateralis stercorarius, the oblong slipmouth, is a marine ray-finned fish, a ponyfish from the family Leiognathidae. It has been recorded from Indonesia, Philippines, New Guinea, Guam and Tonga in the western Pacific Ocean. It lives on inner reef flats and in silt-laden inshore waters at depths greater than 20 metres (66 ft). It attains a maximum recorded total length of 10.2 centimetres (4.0 in). It was first formally described in 1907 as known as Leiognathus stercorarius by the American ichthyologists Barton Warren Evermann (1853-1932) and Alvin Seale (1871-1958) with the type locality given as Bulan, Sorsogon in the Philippines. It was more recently named as Equulites stercorarius, but was re-evaluated in 2015 as part of Photolateralis. It is the type species of the genus Photolateralis.
Leiognathus berbis, the Berber ponyfish, is a species of marine ray-finned fish, a ponyfish from the family Leiognathidae. It is found in brackish and marine waters in the Indian and Pacific Oceans from the Red Sea, Gulf of Aden and Zanzibar east in the Indian Ocean to south-east Asia. Like its relatives, the fish is a demersal species that feeds on small crustaceans and bivalves. Equula berbis is considered by some authorities to be nomen dubium with the taxon it is assigned to being of uncertain placement beyond the family level, the name being thought to probably be a junior synonym of Equulites oblongus.
Leiognathus brevirostris, commonly known as the shortnose ponyfish, is a fish of brackish and marine waters found from Indo-West Pacific to the Indian coasts and off Sri Lanka to China and south of Australia. Like its relatives, the fish is an amphidromous, demersal species which feeds on diatoms, copepods, Lucifer, nematodes and polychaetes. The fish has eight dorsal spines, sixteen dorsal soft rays, three anal spines and fourteen anal soft rays. Fresh specimens possess a golden gleam which fades with dryness.
Equulites klunzingeri, or Klunzinger's ponyfish, is a marine, demersal species of ponyfish from the family Leiognathidae which was originally found only in the Red Sea. It is colonizing the Mediterranean as part of the Lessepsian migration through the Suez Canal.
Secutor insidiator, the pugnose ponyfish or barred ponyfish, is a species of ray-finned fish, a ponyfish in the family Leiognathidae. The barred ponyfish's mineralized skeleton contains apatite and the mineralized tissue contains hydroxylapatite. They have bare heads with nuchal spines and their bodies are a distinctive, reflective silver, frequently imitated by fishermen using silver lures. They have a protracted mouth pointing upward and the tip of the maxilla reaches well below the level of the lower margin of the eye. Barred ponyfish feed on zooplankton, including larval fishes and crustaceans. Body depth is twice or slightly more than standard length, which measures 11.3 cm from the tip of the snout to last vertebra. The lateral line ends before the dorsal fin.
Karalla dussumieri, Dussumier's ponyfish, is a species of marine ray-finned fish, a ponyfish from the family Leiognathidae. It is found in the Indo-Pacific region where it occurs from Madagascar and Réunion east to the Philippines. It is found in schools over substrates consisting of coral sand in coastal waters, although it will also enters estuaries. It feeds on small crustaceans, polychaetes, bivalves, foraminiferans, gastropods and nematodes. This species was first formally described as Equula dussumieri in 1835 by Achille Valenciennes with the type locality given as the Coromandel coast. The specific name honours the French voyager and merchant Jean-Jacques Dussumier (1792-1883), who collected the type.
