Perciformes
See text Perciformes (/ˈpɜːrsɪˌfɔːrmiːz/), also called the Acanthopteri, is an order or superorder of ray-finned fish in the clade Percomorpha.Among the well-known members of this group are perches and darters (Percidae), and also sea basses and groupers (Serranidae).[3] The earliest fossil perciform is the extinct serranid Paleoserranus from the Early Paleocene of Mexico, but potential records of "percoids" are known from the Maastrichtian, including Eoserranus, Indiaichthys, and Prolates, although their exact taxonomic identity remains uncertain.[4][5] 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.
