There are many predators such as larger fish, crustaceans, and some birds that eat some of the eggs and tadpoles. Because bullfrog tadpoles are not very active, they are less likely to be eaten by any animal. However, if spotted, bullfrog tadpoles will be eaten by salamanders and invertebrates. When they become adult frogs, the predators become food for the bullfrogs. Males will stay with their tadpoles and protect them. Males will even take their tadpoles, by digging through mud, to other large bodies of water. They do this if the water is drying up. The tadpoles of a bullfrog are not a favorite food source for fish. This is because of their awful taste. This gives bullfrog tadpoles a better chance in surviving than tadpoles of other frogs. Bullfrog tadpoles spend most of their time not swimming. This makes them less noticeable. Tadpoles of a bullfrog have also raised concerns. Their favorite food is algae and while growing up, they consume large amounts of it. They can also live anywhere where a human house is, if there is water nearby.
