Etymology: Trimma: Greek, trimma, -atos = something crushed (Ref. 45335). More on author: Winterbottom.
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range ? - 41 m (Ref. 86942). Tropical
Indo-West Pacific: Maldives; then from Indonesia and Papua New Guinea to the Solomon Islands, Australia and New Caledonia.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 2.5 cm TL male/unsexed; (Ref. 90102)
(total): 6 - 7;
soft rays: 8 - 9. A species of Trimma with a yellow head, a grey-brown body, and a distinct oval dark spot above and just anterior to the posterodorsal corner of the operculum. This spot is preceded by a shallow groove which extends along the dorsal margin of the operculum. No predorsal scales, posterior half of the nape with a slightly developed longitudinal ridge in the midline, scales present on either side of the ridge with a narrow scaleless gap between them; slight interorbital trench which extends posteriorly barely beyond mid pupil, no postorbital trench; fifth pelvic fin ray unbranched and 50-70% of the length of the fourth (Ref. 52310).
Solitary or in small groups in caves and ledges. Also found in steep seaward slopes in 10-40 m (Ref. 90102).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00891 (0.00427 - 0.01860), b=3.08 (2.91 - 3.25), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
