Morphology | Morphometrics
Dorsal rays IX,12; anal rays III,12; pectoral rays 13. Lateral-line scales 20 + 5. Head naked except for one or two small partly embedded scales dorsally on opercle. Gill rakers 16-18. Body depth 2.6-2.75 in SL. Dorsal profile of snout forming an angle of about 50°, front of head with a slight median ridge. Origin of the dorsal fin a little posterior to preopercular margin; first dorsal spine flexible, slightly longer than second spine, 4.05-4.15 in head length; space between first two dorsal spines two-thirds space between second and third spines. Caudal fin slightly rounded. Pectoral fins short, 1.6-1.7 in HL. Body bright red, edges of scales darker red; membranes of spinous portion of dorsal fin bluish gray, each with a black spot; each of first three membranes of soft portion of fin with a faint black spot (Ref. 57578).

Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref. 82805
= 0.5156 [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), based on all LWR estimates for this BS (Ref. 93245
Trophic Level (Ref. 69278
): 3.3 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (26 of 100) .
