Morphology | Morphometrics
(total): 15 - 17;
soft rays: 16 - 19. Translucent greyish with irregular dark bars/saddles on back and side. Male with large black spot covering pectoral-fin base and black "mask" covering most of head and breast. Female with oblique black bands on anal fin. Head, chest, and pectoral-fin base scaleless; short, lobate orbital tentacle; mandibular pores 3 + 1 + 3. Maximum size to 3.1 cm TL (Ref. 90102).
Adults inhabit rock and coral reefs and may be found in tidepools at depths of 6 m and shallower (Ref. 90102). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).

Estimates based on models
Preferred temperature (Ref. 115969
): 25.3 - 29.3, mean 28.7 °C (based on 1274 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00550 (0.00246 - 0.01227), b=3.08 (2.89 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
