The bases of the dorsal and anal fins are also scaled and form high sheaths in which the fins can be put back. The scales are usually cycloid . The dorsal fin is supported by nine to ten hard and 9 to 17 soft rays. The caudal fin is deeply split. There is a small axillary process above the pelvic fins . Mojarras have 24 vertebrae.
