Description

Family Acestrorhynchidae

Fishes of this family are characterized by very elongate (pike-like) bodies covered with relatively small scales . All teeth are conical and strong canines are present on the premaxilla, anterior part of the maxilla and the dentary. Small conical teeth are present on the ectopterygoid and minute conical teeth have been detected on the mesopterygoid of some species. Other exclusive features of the group are: first infraorbital covering almost completely the maxilla whent the mouth is closed ; a branch of the laterosensory canal on the premaxilla; and rhinosphenoid bone in close contact with parasphenoid . The anal fin is falcate , never bearing hooks in sexually mature males and the origin of the dorsal fin is much nearer to caudal base than the tip of the snout. See Menezes (1969), Menezes (1992), Menezes & Géry (1983), Toledo-Piza & Menezes (1996) and Lucena & Menezes (1998).
