Myliobatidae (Eagle and manta rays)
Etymology: Aetomylaeus: Greek, aetos = eagle + Greek, mylio = mill, grinder (Ref. 45335).
More on author: Gray.
Environment: milieu / climate zone / depth range / distribution range
Ecologia
marino; salmastro associati a barriera corallina; distribuzione batimetrica 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 / Peso / Age
Maturity: Lm 63.0, range 54 - 72 cm
Max length : 200 cm WD maschio/sesso non determinato; (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
Maturità | Riproduzione | Deposizione | Uova | Fecundity | Larve
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).
