The Malakichthyidae 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 ten hard rays and nine to eleven soft rays. The anal fin has three hard and seven to nine soft rays. All species of the Malakichthyidae have 25 vertebrae and seven Branchiostegal rays .

Systematics

The Malakichthyidae family includes 14 species from two genera. All of them were assigned to the Acropomatidae until October 2018 . This fish family was not monophyletic in its earlier composition , 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 the genera Malakichthys , Neoscombrops and their relatives, the sister group of groupers are (Polyprionidae). To get back to monophyletic families, two new families were introduced. For Malakichthys and their close relatives, the name Malakichthyidae was available, the American US in 1910 by the ichthyologist David Starr Jordan and his colleagues Richardson subfamily (Malakichthyinae) combers was introduced (Serranidae) and then only Malakichthys included. The Malakichthyidae can be distinguished from the Acropomatidae by their fin formula .
