Perciformes Perciformes (), also called the Acanthopteri, is an order or superorder of ray-finned fish in the clade Percomorpha. ''Perciformes'' means " perch-like". Among the well-known members of this group are perches and darters ( Percidae), and als ...

Characteristics

Members of Cirrhitoidei are characterised by having the pelvics fins placed relatively far to the posterior of the pectoral fins, The most ventral 5–8 rays of the pectorals are simple and unbranched, typically thickened and sometimes separate from each other. The anal fin normally has 3 spines.
