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 [1] 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. [3] 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. [4] Fishbase places this species in Leiognathus while retaining the striped ponyfish (Aurigequula fasciata) in the monotypic Aurigequula. [1]

The longspine ponyfish reaches a total length of 16 cm (6+14 in). [1] It is distinguished by a long spine on both its dorsal and anal fin. [5]

Found to depths of around 40 m (130 ft), [5] the longspine ponyfish forages on the sea floor, [1] generally in murky environs, [6] consuming fish, crustaceans, arrow worms, nematodes, and shellfish such as bivalves, and gastropods. [1]

Like all members of the ponyfish family, the longspine ponyfish is bioluminescent. The ventral surface glows, which is thought to provide camouflage and confuse predators. [6]

<i>Acanthurus</i> Genus of fishes

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.

<span class="mw-page-title-main">Rabbitfish</span> Genus of fishes

Rabbitfishes or spinefoots are perciform fishes in the family Siganidae. The 29 species are in a single genus, Siganus. In some now obsolete classifications, the species having prominent face stripes—colloquially called foxfaces–are in the genus Lo. Other species, such as the masked spinefoot, show a reduced form of the stripe pattern. Rabbitfishes are native to shallow waters in the Indo-Pacific, but S. luridus and S. rivulatus have become established in the eastern Mediterranean via Lessepsian migration. They are commercially important food fish, and can be used in the preparation of dishes such as bagoong.
