Lots of different predators will prey upon other predators: Golden eagles are well known predators of smaller hawks. Collared lizards will eat other lizards. Crocodilians will feed on other predators, such as monitor lizards, snakes and even lions that come to the water to drink. Many snakes will eat other snakes. Some frogs, like the horned frogs of South America and the African bullfrog, readily feed on other frogs.
King Snakes are killed and eaten by Hawks, Eagles, Owls, Badgers, Racoons and I doubt a Black or Brown Bear would have any problems snacking on them if encountered. King Snakes can be eaten by other snakes as well ...though I haven't found out which snakes are their primary predators yet.he Alaskan King Crab also has several natural predators that  consider them a food source. Fish such as the halibut or pacific  cod are good examples of predators as well a â¦ s sea otters, octopuses  and other types of Crab.
