Etymology: Trimma: Greek, trimma, -atos = something crushed (Ref. 45335); halonevum: Name from 'halo nevus', a skin condition characterized by pale spots with a red centre, referring to the similar spots on the body of the new species (the name was given by Dr. Irving Klinghofer, a Toronto physician). More on author: Winterbottom.
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 1 - 45 m (Ref. 118045). Tropical
Indo-Pacific: Maldives and Christmas Island; Indonesia, Philippines, Papua New Guinea, Solomon Islands, New Hebrides, and, apparently, Society Islands.

Estimates based on models
Preferred temperature (Ref. 115969
): 27.1 - 29, mean 28.1 °C (based on 396 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00454 - 0.02011), b=3.05 (2.88 - 3.22), 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) .
