Dorsal spines (total): 9-10; Dorsal soft rays (total): 11; Pectoral-fin rays: 19-21 (usually: 20); Pelvic rays: I, 5; Vertebrae: 11-12 + 15-16 = 27. Body elongate, head moderately depressed. Rear edge of maxilla ends well in front of eye. Prominent pit present behind upper eye. Preopercular spines short, usually 2 subequal, rarely 3. Supraorbital ridge usually smooth over eye, bearing a few small spines posteriorly. Preorbital spines lacking; a single preocular spine; suborbital ridge largely smooth, bearing 2 spines below eye. Teeth on vomer in 2 separate patches. Lower side of head bicarinate. Iris lappet cirrose. Dermal papillae (10-12 in adults) on upper eye, some simple, some branched, longest not reaching above supraorbital ridge. Interopercular flap usually broader than long, with several subdivisions. Total gill rakers on first gill arch: 5-6 (usually: 6). Oblique scale rows slanting backward above lateral line more or less equal to number of lateral-line scales. Lateral-line scales 50-55 (usually: 52-53), anterior 1-3 scales bearing a weak spine. Scale pores of lateral line with a single opening to the exterior. Max. length: 50.0 cm. Common length: 35.0 cm. Depth range: 1 - 12 m , usually: 2 - 3 m.
Small juveniles all black, gradually changing to the blotched pattern of the adult. Body dark brown above, lower sides frequently with irregular dark brown blotches, pale below, breast with brown streaks in some; All fins mottled with small to large dark blotches.
Cymbacephalus: from Latin, cymba = a boat, skiff, first used by the Phoenicians; Especially the small boat used by Charon to ferry the dead + from Greek, kephale = head.
beauforti: this species is named in honor of the late Dr. L. F. de Beaufort who, in addition to his many notable contributions to ichthyology, at die age of 88 wrote a most informative and encouraging letter to me concerning the need for a revision of the Platycephalidae.
