Myliobatidae (Eagle and manta rays)
Etymology: Aetomylaeus: Greek, aetos = eagle + Greek, mylio = mill, grinder (Ref. 45335).

Environment: milieu / climate zone / depth range / distribution range
экология
морской; солоноватоводный ассоциированный с рифами; пределы глубины 1 - 18 m (Ref. 37816). Tropical; 30°N - 23°S, 51°E - 167°E
Indo-West Pacific: India to China and Indonesia.
Length at first maturity / Size / Вес / Возраст
Maturity: Lm 63.0, range 54 - 72 cm
Max length : 200 cm WD самец/пол неопределен; (Ref. 30573)
With distinctive color pattern and exceptionally long spineless tail over six times the length of the body (Ref. 37816).
Found inshore (Ref. 9862). Inhabits mangrove creeks and protected sandy channels to a depth of at least 18 m; relatively uncommon (Ref. 37816). Active swimmer, travelling long distances; feeds on crustaceans and molluscs (Ref. 68964). Ovoviviparous (Ref. 50449). Caught occasionally by bottom trawl, tangle net and inshore gillnet fisheries. Utilized for its meat, but of limited value as it is not frequently landed (Ref. 58048). Presumably utilized for human consumption in the western central Pacific (Ref. 9862).
Life cycle and mating behavior
половая зрелость | размножение | нерест | икра | Fecundity | личинки
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.
123201): 25.6 - 29.3, mean 28.6 °C (based on 2218 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00119 - 0.01269), 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 ±0.5 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref.
120179): низкий, минимальное время удвоения популяции 4.5-14 лет (Fec assumed to be <100).
Fishing Vulnerability (Ref.
59153): Very high vulnerability (83 of 100).
