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.
Dryopidae
Despite being referred to as aquatic insects, the beetles are unable to swim, clinging to detritus that float. All long-toed water beetles feed on plants that are in the water, but the larvae also prey on small animals and most of them are terrestrial. "Stygoparnus" is the only genus in the family in which both the larvae and adults are aquatic.
