Elasmobranchii (sharks and rays) > Myliobatiformes (Stingrays) > Myliobatidae (Eagle and manta rays)
Etymology: Myliobatis: Greek, mylo = mill + Greek, + Greek, batis,-idos = a ray (Raja sp.) (Ref. 45335).
Eponymy: This is not an eponym but based on a Japanese name; from tobi, the Japanese name for the Black Kite (Milvus migrans) and jei for ray, so literally translating as ‘kite(-like) ray’. (Ref. 128868), visit book page.

Length at first maturity / Size / Weight / Age
A common inshore and offshore species, demersal in intertidal habitats to depths of at east 220 m (Ref.58048). Found from the intertidal to the uppermost continental slope (Ref. 9862, 11230). A carnivore feeding on benthic animals. Ovoviviparous (Ref. 50449). Caught occasionally by inshore, demersal longline fisheries. Utilized for its meat and cartilage (Ref.58048).
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. 123201): 12.8 - 24.7, mean 20.3 °C (based on 176 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5002 [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): 3.5 ±0.37 se; based on food items.
Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).
