Appearance and Anatomy
F. acus reach 16.0 centimetres (6.3 in) SL. Coloration ranges from olive-green to yellow-brown with yellowish undersides. A very distinct irregular dark band, often beset with blotches, extends from the head to the root of the tail. The fins are transparent and the rays have dark spots. Each caudal lobe is normally with a dark band. The male’s snout or rostrum is broader than the female’s. When mature, the male’s rostrum becomes adorned with small bristles known as odontodes. The female’s thinner snouts will remain smooth at all times.
