Eastern Indian Ocean: known only from Western Australia. Was illustrated in color as Epinephelus maculatus by Allen (1985, Ref. 1677) and Sainsbury et al. (1985, Ref. 3131). This species have been much confused with other 'reticulated groupers' in literature, and many museum specimens have been misidentified.

Estimates based on models

Preferred temperature (Ref. 123201 ): 26.4 - 28, mean 26.8 °C (based on 22 cells). Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.01175 (0.00571 - 0.02419), b=3.04 (2.88 - 3.20), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  3.7   ±0.5 se; based on size and trophs of closest relatives Resilience (Ref. 120179 ):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.). Fishing Vulnerability (Ref. 59153 ):  Low vulnerability (23 of 100). Nutrients (Ref. 124155 ):  Calcium = 38.2 [18.7, 77.5] mg/100g; Iron = 0.535 [0.293, 1.100] mg/100g; Protein = 18.5 [17.0, 19.8] %; Omega3 = 0.132 [0.084, 0.206] g/100g; Selenium = 29.9 [17.5, 51.7] μg/100g; VitaminA = 228 [64, 811] μg/100g; Zinc = 1.44 [0.99, 2.00] mg/100g (wet weight);
