Etymology: Trimma: Greek, trimma, -atos = something crushed (Ref. 45335);  macrophthalmum: 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.

Estimates based on models

Preferred temperature (Ref. 115969): 24.1 - 28.8, mean 27.5 °C (based on 420 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 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).
Widerstandsfähigkeit (Ref. 120179):  hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).
Verwundbarkeit (Ref. 59153):  Low vulnerability (10 of 100) .
Nutrients (Ref. 124155):  Calcium = 341 [149, 875] mg/100g ; Iron = 1.3 [0.7, 2.6] mg/100g ; Protein = 18.4 [16.4, 20.2] % ; Omega3 = 0.198 [0.087, 0.417] g/100g ; Selenium = 19.4 [8.3, 46.2] μg/100g ; VitaminA = 153 [38, 553] μg/100g ; Zinc = 2.65 [1.51, 4.51] mg/100g (wet weight);
