Etymology: Trimma: Greek, trimma, -atos = something crushed (Ref. 45335); gigantum: Named for the Greek word 'gigas, gigantas' meaning giant, referring to its extremely large size (informally referred to as Trimma RW sp 90, undescribed species, in litt.). More on authors: Winterbottom & Zur.

Morphology | Morphometrics
soft rays: 7 - 9. This species is a member of the T. tevegae species complex (sensu Winterbottom 2005) with a broad interorbital space and a greatly expanded first haemal arch. It is further characterized by 15-18 predorsal scales; the second and third dorsal spines elongate; a fleshy, longitudinal ridge in the interorbital midline; absence of postorbital trenches; scales covering the cheek and opercle; the fifth pelvic fin ray usually branched dichotomously once; a pattern of six dark saddles across the dorsum on a pale yellow background; and, large adult size (to about 30 mm SL) (Ref. 59339).
Inhabits outer reef slopes in caves and crevices in 57-73 m (Ref. 90102).

Preferred temperature (Ref. 115969
): 27.2 - 28.2, mean 27.8 °C (based on 7 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00475 - 0.02204), b=3.03 (2.85 - 3.21), 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) .
