Morphology | Morphometrics
soft rays: 19 - 20. This species is distinguished by having the following characters: D III, XIV, 10, with first dorsal fin lower than second dorsal fin; A I,19-20; pored lateral line scales 18-20, notched scales 17-19; mandibular pore pattern 3+1+3; supraorbital and nasal cirrus slender and long; body color pale or light yellowish with 4 brownish-yellow or reddish-brown bars below second and third dorsal fins and caudal peduncle; behind base of pectoral fin is a brownish-black or black saddle mark; head pale with scattered melanophores, with some males densely spotted resembling a black mask on overall head; dorsal fins reddish to orange with second dorsal membrane dusky near the base; other fins are pale yellow to yellow; supraoccipital sensory canal forms a flattened curve anterior to first dorsal fin (Ref. 79877).
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
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this 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) .
