Taille / Poids / Âge
Maturity: Lm ? range ? - ? cm
Max length : 7.5 cm TL mâle / non sexé; (Ref. 7251)
Rayons mous dorsaux (Total) : 7 - 37; Épines anales: 2. Common amongst Labrisomids: small, often elongate fishes; largest species about 20 cm standard length, most under 10 cm standard length. 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; all fin rays, including those of caudal, unbranched (simple). Cycloid (smooth to touch) scales present at least posteriorly on body. Body coloration: varying from drab to brilliant hues; usually with irregular vertical bands, spots, or marbled pattern. Species distinguished by: length of shortest pelvic-fin ray half, or less than half, length of longest ray; pectoral-fin rays usually 14; 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 and some equal in size; two or more cirri on each side of nape just anterior to dorsal-fin origin; 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); lateral-line tubes or canals present at least anteriorly on body; dorsal fin consisting of spines and 7 to 37 segmented rays (Ref.52855).
Occurs from rocky and rubble shores with algal mats to reefs and seagrass beds.
