Etymology: Trimma: Greek, trimma, -atos = something crushed (Ref. 45335); volcana: Named for Volcanus, Roman god of fire, referring to the amber-red spots on an earthy brown background that resemble numerous small, volcanic vents on a lava field, and is suggestive of the hot-spot origins of the Comores Islands; noun in apposition.

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 10 - 11; Anal spines: 9 - 11. Diagnosis: Characterized by having large spots on the head and body; moderate to well-developed interorbital and postorbital trenches; scales on the pectoral and pelvic fin bases, except on cheeks, opercles, or midline of the nape; a posterior nostril which is adnate to the eye; a fifth pelvic fin ray that is 80-9% of the fourth and is branched dichotomously twice (Ref. 57687).

Estimates based on models

Preferred temperature (Ref. 123201): 26.9 - 28.9, mean 27.5 °C (based on 214 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01023 (0.00477 - 0.02194), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

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).
