King rail
This rail forages in shallow water near cover and eats mainly aquatic insects and crustaceans. It forages by probing the mud while moving around in shallow water.
Japanese eagle ray
The Japanese eagle ray is demersal, usually inhabiting sea floors and feeding on benthic animals. In particular, it is known to eat crustaceans, fish, and sometimes benthic plants. Like all mylobatids, the species is ovoviparous. 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.
