Etymology: Trimma: Greek, trimma, -atos = something crushed (Ref. 45335); dalerocheila: From the Greek daleros for hot or fiery, and cheilos for lip, in allusion to the fiery red snout and lips of this species (Ref. 46430). More on author: Winterbottom.
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 3 - 48 m (Ref. 46430), usually 20 - 40 m (Ref. 46430). Tropical

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 2.0 cm SL male/unsexed; (Ref. 46430)
soft rays: 7 - 11;
Vertebrae: 26. Brick-red in color, usually with two paler bars (one across pectoral base, the other centered on the space between the two dorsal fins); snout and chin fiery red, broken by two pale horizontal stripes from the dorsal and ventral margins of the pupil, respectively. The dorsal stripe passes anteriorly across the nostrils, the ventral stripe crosses the upper jaw and may continue onto the chin (Ref. 46430).
Collected from lagoons as well as from oceanic drop-offs (Ref. 46430). Forms schools and feeds on plankton (Ref. 46430).

Estimates of some properties based on models
Preferred temperature (Ref. 115969
): 18.9 - 28.2, mean 26.8 (based on 12 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00871 (0.00412 - 0.01842), b=3.09 (2.92 - 3.26), 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) .
