As wrasse-like (Labroidei) a subordination from the order of the perch-like (Perciformes) is called in many systematics . Which are in the subordination families of the wrasses (Labridae), the parrot fish (Scaridae) that Odacidae that damselfish (Pomacentridae), the surfperch (Embiotocidae) and the cichlids (Cichlidae) provided.

features

The reason for the assumed relationship is the intricately constructed jaw and pharynx apparatus, which enabled versatile adaptations to different diets. However, DNA sequence analyzes and comparisons do not reveal any relationship between wrasse, parrot fish and odacids on the one hand and cichlids, surf perches and damselfish on the other. The similar skull anatomy must have arisen several times independently of one another.

A new taxonomic group, the ovalentaria, is proposed for the cichlids, surf perches, damselfish and some other taxa related to them , the relationship of which is based primarily on molecular biological studies and is only supported by morphological features on the eggs of the animals.

In addition, the parrotfish and odacids, which were previously placed in the rank of independent families, belong phylogenetically to the wrasse, so that they remain as the only family of labroids.
