Life Cycle
provided by Fishbase
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).
Trophic Strategy
provided by Fishbase
Found from the intertidal to the uppermost continental slope. Lives on the sandy areas in the rocky regions of the Japanese and the East China seas (Ref. 9137). Also inhabits coral reefs (Ref. 58534). A carnivore feeding on benthic animals (Ref. 9137).

Biology
provided by Fishbase
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).

Japanese eagle ray
provided by wikipedia EN
The Japanese eagle ray (Myliobatis tobijei), also known as the cowhead eagle ray or kite ray[3] is a ray species in the family Myliobatidae.[4]
Description
The Japanese eagle ray grows to be up to 150 centimeters long, and has a disc at least 114 centimeters wide.[1] It is yellow-brown in color, and usually contains darker spots. It has rather long stinging spines, and its claspers are less than one-tenth the width of its disc. Each jaw of the species contains 7 rows of teeth.[3]
Behavior
The Japanese eagle ray is demersal, usually inhabiting sea floors and feeding on benthic animals.[3][5] In particular, it is known to eat crustaceans, fish, and sometimes benthic plants. Like all mylobatids, the species is ovoviviparous. Embryos initially feed on yolk. They later receive nourishment by indirectly absorbing uterine fluid from their mother. Little else is known about the biology of this species.[1][3]
Distribution, threats, and conservation
The Japanese eagle ray lives in the waters of East Asia, particularly in Japan, Korea, and China. It is also found in Indonesia and the Philippines.[2] It is a tropical marine species, and lives in depths of over 220 meters.[1]
The species is sometimes caught as a bycatch. It is also sometimes caught intentionally for its meat, as well as for its cartilage.[2] Little else is known about its population and threats. There are currently no conservation measures taking place for this species, and it is listed as Vulnerable by IUCN.[1]
Parasites
The Japanese eagle ray is the host of the following parasitic species:[3]
