What Do Bullfrogs Eat?

An American bullfrog is the largest frog in North America, which are mostly found in the Southern part of the United States. These bullfrogs are not abundant because people used to kill them to eat their legs, which is why their population continues to decrease. Bullfrogs are easily identifiable due to their big size and their immense ability to leap. They are such fascinating creatures that certainly need to be protected.

A bullfrog’s diet

Bullfrogs normally eat all kinds of insects, baby mice and feeder fish. Actually, bullfrogs are voracious eaters, they eat a lot, and they can eat any animal that they can easily swallow. Crayfish, insects, minnows, worms, frogs and even other bullfrogs, baby birds, small turtles, snakes, and other minute animals are potential prey.

When do they hunt?

They capture their prey, mostly at night for fear of other predators. Bullfrogs have many natural enemies, especially when they are at the early stages of their life cycle. Both tadpoles and young bullfrogs are eaten by snakes, turtles, fish and birds while adult bullfrogs can eat mice and baby rats. They will eat anything they can fit in their mouth. If you are an owner of a bullfrog, then keep in mind that grasshoppers can kill them or make them very ill, so never feed your pet with grasshoppers.

Special care for bullfrogs

The most important thing that you need to keep in mind if you are planning to keep more than one bullfrog at a time is that they usually eat anything smaller than themselves, even other small frogs. If you have tadpoles to take care of, then you need to put them in a separate aquarium and make sure that the water in the aquarium should be filtered. Don’t put any fish along with the tadpoles because the fish might harm them. Tadpoles feed on flake food, pallets, algae, and water plants. Just place three to four tadpoles in one aquarium and when they are big enough, you can feed them bloodworm. The tadpole stage can last anywhere between six months to two years.

About American Bullfrog

Bullfrogs are also known as American bullfrogs, and they are naturally found in ponds, lakes and swamps. The average size of a bullfrog, without stretching its legs, is 9 to 15 cm and 17 to 25 cm with its legs stretched. Research has shown that bullfrogs are animals that can eat any other animal, as long as it is smaller than themselves, including their own species. Bullfrogs normally feed on rodents, little turtles, small bullfrogs and bats along with other invertebrates that are usually eaten by other ranid frogs or true frogs. Bullfrogs also have the ability to capture and eat large and strong aquatic animals. An adult bullfrog may eat insects, annelids and even crustaceans.
