Callionymoidei

The lyrefish (Callionymoidei) are a group of perch relatives (Percomorphaceae). They are bottom-dwelling sea creatures.

features

The fish have a broad, flat head, a small mouth and a scaleless, elongated body. Usually lyrefish species have two clearly separated dorsal fins , the first with one to four flexible fin spines (absent in Draculo ). The pelvic fins have a fin spine and five soft rays. The number of vertebrae is 21 to 23, of which seven or fewer are trunk vertebrae. The two frontal bones have grown together, their front part is reduced and is partially replaced by the mesethmoid, another skull bone.

External system

Traditionally, the lyre-fish-like are placed in the order of the perch-like (Perciformes), which is poly- and paraphyletic in its old composition . The comparison of DNA sequences , however, reveals a close relationship with the pipefish-like (Syngnathiformes) and both Betancur-R. and colleagues as well as Near and coworkers assign the Callionymoidei in their new system of bony fish to this order. The relationship between these outwardly quite different groups is based exclusively on the comparison of DNA sequences and has not yet been supported by morphological autapomorphies . Possibly the lyrefish are the sister group of the flying cocks (Dactylopteroidei).

Internal system

There are two families within the lyrefish species, 22 genera and more than 200 species.
