African rail
These birds probe with their bill in mud or shallow water, also picking up food by sight. They mainly eat insects, crabs and other small aquatic animals.
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.
