Perciformes are spinny finned fish characterized by their fins. The dorsal and anal fins are divided into anterior spiny and posterior soft-rayed portions, which may be partially or completely separated. The pelvic fins usually have one spine and up to five soft rays, positioned unusually far forward under the chin or under the belly. Scales are usually ctenoid, although sometimes they are cycloid or otherwise modified.
