Morphology | Morphometrics
soft rays: 55 - 57. Yellowish brown head and body; greyish brown dorsal and anal fin; dorsal fin membranes with numerous tiny black spots; pale yellow pectoral fin with black spot on upper base; yellow caudal fin with black upper margin and black filamentous outer lobes. Segmented caudal rays 11; adults of both sexes with elongate and filamentous caudal fin outer lobes (much longer in males (up to 50% of SL); dentary incisors with arrowhead-shaped tips; 4 interorbital pore; body depth ca. 20-22 in SL. Maximum size to 27 cm TL (Ref. 90102).
Adults are found in muddy sand bottoms (Ref. 90102). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).
