Short description
Hình thái học | Sinh trắc học
Các tia vây lưng cứng (tổng cộng): 19; Tia cứng vây hậu môn 2; Tia mềm vây hậu môn: 19. Common amongst Labrisomids: small, often elongate fishes. Head usually with cirri or fleshy flaps on anterior nostrils, eyes, and laterally on nape; gill membranes continuous with each other across posteroventral surface of head. Each jaw with an outer row of relatively large, canine-like or incisor-like teeth, often with patches of smaller teeth behind; teeth usually also present on vomer and often on palatines (roof of mouth). Dorsal and anal fins long, frequently highest anteriorly; dorsal-fin spines often flexible, outnumbering segmented dorsal-fin soft rays; 2 usually flexible spines in anal fin; pelvic fins inserted anterior to pectoral-fin bases, with 1 spine not visible externally and only 2 or 3 segmented rays; all fin rays, including those of caudal, unbranched (simple); lateral-line tubes or canals varying from complete (extending entire length of body) to present only on anterior portion of body. Cycloid (smooth to touch) scales present at least posteriorly on body. Body coloration: usually with irregular vertical bands, spots, or marbled pattern. Species distinguished by: specimens 2.8 to 4.0 cm SL; dorsal-fin spines usually 19, segmented anal-fin rays usually 19; length of shortest pelvic-fin ray more than half length of longest ray; pectoral-fin rays usually 13; pelvic-fin soft rays 3 (innermost ray may be reduced in length and folded over middle ray); scales in lateral-line series 40 to 69 (some scales in posterior portion of lateral line may lack sensory tubes, but are included in count) maxillary bone exposed posteriorly; patches of small teeth behind outer row of large teeth in at least upper jaw; palatine teeth present, some distinctly larger than those on vomer; two or more cirri on each side of nape just anterior to dorsal-fin origin; dorsal and anal fins pale or with very faint markings; peritoneum white with scattered large melanophores; opercular ocellus absent (Ref. 52855).
Occurs from rocky and rubble shores with algal mats to reefs and seagrass beds.
