Etymology: Trimma: Greek, trimma, -atos = something crushed (Ref. 45335); macrophthalmus: Origin of name not given, but presumably from ‘macro’ for large and the Greek noun ‘opthalmos’, meaning eye; originally spelled as ‘macrophthalmus’, and the spelling is retained because the second half of the specific name is a noun; thus treated as noun in apposition.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 5 - 35 m (Ref. 90102). Tropical
Indo-West Pacific: East Africa (including Sodwana Bay, South Africa) east to Fiji, north to Japan. Recently recorded from Tonga (Ref. 53797).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 2.5 cm TL male/unsexed; (Ref. 2798)
soft rays: 8 - 9. Very similar to T. okinawae but lacks predorsal scales (Ref. 37816). Body with ctenoid scales except ventral midline and pectoral base with cycloid scales. Transverse scales 7-8. Mouth slightly oblique upwards. Second spine longest in 1st dorsal; rays of 2nd dorsal nearly equal; anal fin similar to 2nd dorsal; pectoral reaches to vertical of anus; pelvic fins without frenum but connected to basal membrane (Ref. 43541); characterized further by body with greyish matrix with dense red to orange spotting on head and body; median fins with faint yellow spotting; pair of large red spots on base of pectoral fin; longitudinal scale series 26-27; cheek and opercle without scales; depth of body 3.9-4.2 in TL (Ref. 90102).
Bottom-dweller of seaward reefs (Ref. 37816). Usually in small groups in caves and under ledges (Ref. 90102).

Estimates of some properties based on models
Preferred temperature (Ref. 115969
): 24.1 - 28.8, mean 27.5 (based on 420 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00871 (0.00414 - 0.01834), b=3.08 (2.90 - 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) .
