Etymology: Trimmatom: Greek, trimma, -atos = something crushed + Greek, tomos = cut (Ref. 45335); offucius: From its orange-red bar beneath the eye; Noun in apposition.. More on author: Winterbottom.
Environment / Climate / Range
Marine; demersal; depth range 15 - 50 m (Ref. 38635), usually 20 - 50 m (Ref. 38635). Tropical
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 1.4 cm SL male/unsexed; (Ref. 38635)
Western Indian Ocean: Chagos Archipelago.
Inhabits mainly oceanic drop-offs; in and around caves in vertical walls. Probably a schooling fish; feeding on plankton but radiolarians in the gut may indicate some feeding off the substrate (Ref. 38635).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00407 (0.00165 - 0.01005), b=3.10 (2.88 - 3.32), based on LWR estimates for this Subfamily-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.0 ±0.3 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
