Etymology: Trimma: Greek, trimma, -atos = something crushed (Ref. 45335); tauroculum: Name from Latin 'taurus', meaning bull, and 'oculus' for eye, in allusion to the distinctive bulls-eye like marking above the pectoral fin which characterizes this species.. More on author: Winterbottom.

Marine; reef-associated; depth range 27 - 73 m (Ref. 59339). Tropical

Morphology | Morphometrics
soft rays: 8. The species is characterized by the absence of scales on the cheek, opercle and midline of the nape; fifth pelvic fin ray branched sequentially once; a moderate interorbital trench;
a short and narrow postorbital trench; color of living specimens red with a white belly, a large brown-black spot larger than the eye immediately above the pectoral fin base and numerous smaller dark spots across the nape; and in preserved specimens the dark spots remain but the ground color is yellow. Differs from its congeners by the very large 1.25 eye diameter brown-black spot above the pectoral fin base and the rows of smaller brown spots on the nape separated by a honeycomb pattern (Ref. 59339).

Preferred temperature (Ref. 115969
): 27.9 - 28.7, mean 28.4 (based on 4 cells).
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
