Short description Morphology | Morphometrics

Dorsal spines (total): 18; Dorsal soft rays (total): 7-37; Anal spines: 2. Common amongst Labrisomids: small, often elongate fishes; largest species about 20 cm SL, most under 10 cm SL. 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). 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: dorsal fin consisting of spines usually 18 and 7 to 37 segmented rays; pectoral-fin rays usually 14; 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); total nasal cirri (both sides) usually more than 7; two or more cirri on each side of nape just anterior to dorsal-fin origin; combination of conspicuous dark spot on anterior dorsal-fin spines and a dark ocellus extending from bases of posterior dorsal-fin spines onto dorsal contour of body not present; no small teeth behind large teeth in outer row; pectoral-fin base scales, when present, smaller than those on body; length of shortest pelvic-fin ray (third ray very difficult to see) contained fewer than 4 times in length of longest ray; maxillary bone sheathed; teeth absent on palatines (Ref.52855).

Biology     Glossary (e.g. epibenthic)

Inhabits shallow sandy and rocky areas of coral reefs (Ref. 9710). Feed on copepods, amphipods, delicate algae and occasionally of eggs of Abudefduf (Ref. 5521).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00468 (0.00183 - 0.01196), b=3.10 (2.87 - 3.33), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.1   ±0.35 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months ().
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
