The Lobotidae are a family of fish from the order of the surgeon fish-like (Acanthuriformes). The family includes three genera, the three-tailed perch ( Lobotes ), the tiger perch ( Datnioides ) and Hapalogenys with a total of 15 species. The fish live almost all over the world close to the coast in moderately tempered, subtropical and tropical seas, sometimes also in brackish and fresh water. Outwardly, the fish resemble the only very distantly related sun bass . The caudal fin and the soft-rayed sections of the dorsal and anal fin located far back are rounded. The palate is toothless.
Systematics
The Lobotidae family was introduced to the genus Lobotes in 1861 by the American ichthyologist Theodore Nicholas Gill . In Joseph S. Nelson's Fishes of the World , a standard work on fish systematics, the tiger bass also belong to the family, which in many other taxonomies form an independent family, the Datnioididae. The genus Hapalogenys , which used to be part of the sweetlips and grunts family (Haemulidae), later became the only genus in the Hapalogenyidae family. The morphology of the larvae, especially the partial thorns of the skull and its scaling, the early development of the pelvic fins that set relatively far forward, the color and body shape, as well as a characteristic of adult fish (the morphology of the upper gill arches ) are, however, an indication of a close Relationship of Lobotes , Datnioides and Hapalogenys . The Australian ichthyologists Anthony Gill and Jeffrey M. Leis therefore also assigned Hapalogenys to the Lobotidae in October 2019 . At the same time they put the Lobotidae in the order of the surgeon fish-like (Acanthuriformes). The Lobotidae share a unique trait (a synapomorphism ) with the rest of the surgeonfish , which was used to diagnose the order. In the larvae and adult specimens of the Lobotidae and the other surgeonfish species, the regrowing teeth grow on the outside of the jaw and replace their predecessors in groups. The Lobotidae are the basal sister group of the remaining surgeon fish-like.
