Etymology: Aetomylaeus: Greek, aetos = eagle + Greek, mylio = mill, grinder (Ref. 45335). More on authors: Müller & Henle.
Environment: milieu / climate zone / depth range / distribution range
Marine; benthopelagic; depth range - m (Ref. ), usually - m (Ref. ). Tropical; 0°C -
Indo-West Pacific: Red Sea to China, south to Indonesia. Validity of this species questioned in Compagno's 1999 checklist (Ref. 35766).

Maturity: Lm ?  range ? - ? cm
Found inshore (Ref. 9862). Ovoviviparous (Ref. 50449). Presumably utilized for human consumption in the western central Pacific (Ref. 9862).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449).

Estimates based on models
Preferred temperature (Ref. 115969
): 24.7 - 29.1, mean 28.1 °C (based on 1798 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00121 - 0.01252), b=3.08 (2.83 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.8 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Vulnerability (Ref. 59153
): High to very high vulnerability (69 of 100) .
