Micropogonias

Micropogonias was first proposed as a genus in 1831 by the French naturalist and ornithologist Charles Lucien Bonaparte, with Micropogon lineatus being its type species by virtue of being a replacement name. but the 5th edition of Fishes of the World does not recognise subfamilies within the Sciaenidae, which it places in the order Acanthuriformes. ==Etymology==

Micropogonias combines micro, which means "small", with pogonias meaning "bearded", an allusion to the small barbels on the chin of the type species. ==Species==

Micropogonias has the following species classified within it: • Micropogonias altipinnis Günther, 1865 (Tailfin croaker) • Micropogonias ectenes. (Jordan & Gilbert, 1883) (Slender croaker) • Micropogonias fasciatus (de Buen, 1961) • Micropogonias furnieri (Desmarest, 1823) (Whitemouth croaker) • Micropogonias megalops (Gilbert, 1890) • Micropogonias undulatus (Linnaeus, 1766) (Atlantic croaker) However, Catalog of Fishes recognises the following species as valid within Micropogonias: Catalog of Fishes treats M. ectenes as a synonym of M. altipinnis and M. fasciatus as a synonym of Paralonchurus peruanus. ==Characteristics==

Micropogonias croakers have an elongated body, with a high dorsal profile and an almost flat ventral surface and a conical head. The preoperculum has between 10 and 14 spines on its margin with between 2 and 5 robust spines at its angle. The mouth is under the snout and has villiform teeth arranged in bands, with the outer row in the upper jaw being made up of slightly larger teeth than the rest. The anterior, spiny part of the dorsal fin is quite tall, with the third spine being longer than the others, while the soft rayed part of the dorsal fin is supported by between 26 and 30 soft rays. The anal fin has two spines, the second spine being robust and half the length of first anal fin ray, and between 7 and 9 soft rays. The caudal fin has sharp point. The largest species is the tailfin croaker (M. altipinnis) which has a maximum published total length of while the smallest, M. megalops, has a maximum published total length of . ==Distribution and habitat==

Micropogonias croakers are found in the eastern Pacific Ocean and the Western Atlantic Ocean, with two species (M. furnieri and M. undulatus) in the Atlantic (M. cevegei sensu Catalog of Fishes is also found in the Atlantic) and the remaining four in the eastern Pacific. These fishes live in estuaries and in inshore waters with sand or mud substrates. == References ==
