Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 14 - 17; Dorsal soft rays (total): 7 - 11; Anal spines: 1; Anal soft rays: 17 - 21. Small and slender supraorbital tentacle; in males, first spine of first dorsal fin higher than first spine of second dorsal fin; in females, first dorsal fin a little less than 50% shorter than second dorsal fin; females whitish, with fine black dots, bearing a reticular red or brown pattern, isolating the white into 2-3 longitudinal rows of blotches; male coloration similar but generally darker. Dorsal rays III + XI-XIII + 7-10; lateral line interrupted, 14-20 + 14-21; mandibular pores 3-4 + 1 + 3-4 (Ref. 54980).
Female members of the Tripterygiidae have eggs that 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).

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00562 (0.00258 - 0.01228), b=3.08 (2.89 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 3.2 ±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.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
