The Acropomatidae are a fish family from the group of perch relatives (Percomorphaceae). They live in the Atlantic , Pacific and Indian Oceans at depths of several hundred meters.

features

The fish are 10 to 40 centimeters long. They have two dorsal fins , which are supported by eight to nine hard rays and ten soft rays. The anal fin has three hard and seven to nine soft rays. All species of the Acropomatidae have 25 vertebrae and seven Branchiostegal rays . The species of the genus Acropoma have luminous organs in the abdominal region, which is why they are referred to in English as "lanternbellies" or "glowbellies". Her anus sits far ahead, the belly fin base, a feature that also in close comber Bullisichthys caribbaeus and the Kardinalbarsch ostorhinchus gularis occurs.

Systematics

The Acropomatidae family was introduced in 1893 by the American ichthyologist Theodore Nicholas Gill . It originally comprised ten genera and around 40 species . In this composition, however, the family was not monophyletic , but consisted of three clades with different positions in the phylogenetic tree. Thus forming Acropoma , the type genus of Acropomatidae family, along with Doederleinia the sister group of Scombropidae while z. B. the genera Malakichthys and Neoscombrops and their close relatives are the sister group of the wreck perch (Polyprionidae). To get back to monophyletic families, the families Malakichthyidae ( Jordan & Richardson, 1910 ) and Synagropidae ( Smith , 1961 ) were revalidated, so that only two genera remain in the family Acropomatidae, Acropoma with nine species and the monotypical genus Doederleinia . The three fish families can be distinguished by their fin formula .

Fossil record

A fossil relative, Acropoma lepidotus, is known from the middle Eocene of the northern Italian Monte Bolca Formation, which arose from Tethys deposits .
