Morphology | Morphometrics
soft rays: 8. This species is distinguished by the following characters: predorsal midline with 8-9 scales; usually cycloid scales along the upper border of the opercle in up to 3 horizontal rows; without cheek scales; second dorsal spine very elongated, reaching posteriorly to the end of the second dorsal fin or beyond this (in specimens >18 mm SL); pectoral fin with branched middle rays; fifth pelvic fin ray branches once dichotomously and is 52-64% the length of the fourth ray; basal membrane connecting the inner margins of the fifth pelvic fins rays is less than 15% the length of the fifth ray (Ref. 95906).
Most Trimma species are found between 10-30 m, with relatively few occurring in depths shallower than this. In this case of Trimma irinae, this species occur at depths below about 50 m (Ref. 95906).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00454 - 0.02011), b=3.05 (2.88 - 3.22), 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.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
