The dragon fish (Trachinoidei) are no longer recognized as a natural kinship group, which was traditionally placed with the perch-like (Perciformes). The majority of the species live in tropical seas.

features

Hardly any synapomorphies could be determined for the dragon fish . Doubtful characteristics reported for group monophyly are:

  1. a spur on the pelvic fins ,
  2. short and wide pectoral fins radiate .

Systematics

Northern Electric Stargazer

They belonged to twelve families, over 50 genera and almost 250 species:

The dragon fish are now considered polyphyletic . According to recent molecular biological studies, the sand fish are related to the bull relatives (Cottoidei), the weever with the saw perch (Serranidae) or the Antarctic fish (Notothenioidei). A relationship with the Antarctic fish is also assumed for the beak fish. The deep-sea Chiasmodontidae, on the other hand, are said to be relatives of the mackerel-like (Scombroidei) and the medusa-like fish (Stromateoidei).

For the monophyletic core group of dragon fish, consisting of sand eels, Cheimarrhichthyidae, sand perches and sky gazers, a new subordination, the paratrachinoidei , was proposed by some ichthyologists at the Muséum national d'histoire naturelle in Paris . Betancur-R. and colleagues placed these taxa in the order Uranoscopiformes in their revision of the bony fish systematics .

A close relationship could also be proven for the families of the slim sky-gazers, the sand cave fish, the sand divers and the subfamily Hemerocoetinae from the family of the beak fish .
