All Baldwinella Species: Dorsal fin with 10 spines and 13-16 rays; anal fin with 3 spines and 6-13 rays; branched caudal-fin rays 13; caudal fin deeply forked. Most of upper edge of operculum free, not connected by skin to body. No scaly flap of skin joining upper part of pectoral-fin base to body. . Head larger, its length contained 2.3-3.3 times in standard length; pelvic-fin length 24-38% standard length. Preopercle without a large antrorse spine; preopercle not expanded posteriorly, the serrae at the angle only slightly enlarged. Middle opercle spine not reaching edge of operculum. Front nostrils variously shaped, but always closer to rear nostrils than to upper lip. Supramaxilla absent. Teeth fixed (not depressible). Upper jaw moderately protrusile; jaw teeth distinct; vomer and palatines with teeth; body depth 27-48% standard length. Posterior process of premaxilla broad and near tip of alveolar ramus. Branchiostegal rays 7. Total gill rakers on first arch 34-44. Lateral scale series about the same number (39-55) as the lateral-line scales (42-53); circum-caudal-peduncular scales 22-29. Soft dorsal and anal fins mostly naked; maxilla and most or all of interorbital area naked (FAO 2002).
