Roosterfish can reach over in length and over in weight. Despite being a very popular sport fish, Roosterfish are an understudied species.
== Taxonomy == The scientific name of the roosterfish is Nematistius pectoralis. It was first described by American ichthyologist, mammalogist, malacologist, and librarian Theodore Gill in 1862 based on specimens from the Smithsonian Institution collected by John Xantus. Roosterfish are ray-finned fishes and therefore reside in the class Actinopterygii. They are one of the largest fish in the order Carangiformes. Roosterfish are the sole member of the family Nematistiidae and the suborder Nematistioidei. They are a unique group with no close relatives, although they appear to be the sister group to the Menoidei (comprising the moonfish and billfishes).
