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 authors: Winterbottom & Emery.
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 15 - 50 m (Ref. 38635), usually 20 - 50 m (Ref. 38635). Tropical
Western Indian Ocean: Chagos Archipelago.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 1.4 cm SL male/unsexed; (Ref. 38635)
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 based on models
Preferred temperature (Ref. 115969
): 27.7 - 28.2, mean 28 °C (based on 2 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00575 (0.00261 - 0.01268), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
