Hyporhamphus is a genus of fish from the half- beak family(Hemiramphidae), which occurs worldwide in tropical and subtropical seas and with some species also in freshwater.

features

Hyporhamphus species are small to medium-sized, elongated fish that can grow to be 15 to 40 centimeters long. The lower jaw is drawn out long, the upper jaw is short and triangular when viewed from above. The nostrils sit in a pit right in front of the eyes. Pectoral and pelvic fins are short; The dorsal and anal fins are arranged far back. All fins are without hard rays. The pelvic fins have six rays . The scales are relatively large and round scales .

Systematics

The genus Hyporhamphus was first described in 1859 by the American ichthyologist Theodore Nicholas Gill together with its type species , Hyporhamphus tricuspidatus (now a synonym of Hyporhamphus unifasciatus ). It is assigned to the half- beaked family (Hemiramphidae), which was also introduced by Gill in 1859. As a study from 2004 showed, however, this is not monotypical . While the relationship to the group type genus Hemiramphus the sister group of the flying fish is (Exocoetidae) is Hyporhamphus together with Arrhamphus (2 types), and the two monotypic genus Chriodorus and Melapedalion closer to the garfish used (Belonidae). The name "Hyporhamphidae" was proposed for the family group around Hyporhamphus .

species

Almost 40 species belong to the genus Hyporhamphus :
