Short description Morphology | Morphometrics

Body moderately slender and compressed; head somewhat small and pointed; teeth caniniform, enlarged, and somewhat crooked, two anterior pairs in each jaw; posterior end of upper jaw with one protruding, forward directed canine on each side; dorsal fin continuous, with 9 spines; lateral line with 28 scales; body blue green, with a dark, vertical bar near posterior edge of pectoral fin, preceded by a very marked yellow spot; all fins except pectorals, blue, speckled with red or light colored spots and stripes (Ref. 55763).

Biology     Glossary (e.g. epibenthic)

Found over sand and gravel bottoms near coral reefs. Adults are solitary but juveniles form aggregations, sometimes with other species of wrasses. Feeds on mollusks, brittle stars, sea urchins and crabs. Hides under the sand to sleep and to seek shelter, in cases of danger.

Estimates of some properties based on models

Preferred temperature (Ref. 115969): 20.6 - 28.5, mean 25.9 (based on 62 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00469 - 0.02134), b=3.08 (2.91 - 3.25), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.0   ±0.61 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate vulnerability (37 of 100) .
