Have you been wondering about what eats frogs? Frogs are easy prey for many animals because of their size, so they have a lot of predators that feast on them. Among animals that eat frogs are birds, snakes, fish, alligators, mammals, turtles, and other frogs.

At every stage of a frog’s life, whether eggs, tadpoles, froglets, or adult frogs, they suffer from predation; predators like lizards, foxes, salamanders, ducks, newts, hawks, kites, owls, and even some humans eat frogs.

In this article, we will look at some of the top frog predators in the world.

We will discuss their hunting strategies and how frogs have evolved to defend themselves against these predators.

Let’s get down to what eats frogs!

What Eats Frogs?

Lots of different kinds of animals enjoy eating frogs. Birds such as herons, egrets, ducks, geese, storks, cranes, gulls, terns, loons, and even songbirds are among the many predators that feed on frogs.

Some species of reptiles, such as snakes, lizards, and alligators, eat frogs.

Fish such as bass, catfish, pike, and perch will eat the eggs and tadpoles of frogs if they find them in bodies of water.

Mammals such as raccoons, skunks, weasels, and foxes are among the predators that feed on adult frogs.

Some species of frogs, such as the bullfrog, and other amphibians, such as the toad, will consume other frogs.

Are Frogs Predators Or Prey?

Frogs can be both predators and prey in their environment. They are classified as predators due to the fact that they feed on the flesh of other animals, namely insects, worms, and spiders.

They are considered prey because to the fact that other species, such as snakes, birds, and fish, consume them for food.

Although tadpoles are often herbivorous, adult frogs consume only meat therefore are carnivores.

In most food chains, adult frogs are typically found as consumers at a secondary or tertiary level.

Several frog adaptations allow them to be predators and prey in their environment.

For instance, they have lengthy tongues that are covered with a sticky substance that they utilize to catch their prey.

They also have excellent eyesight and hearing, both of which aid them in detecting potential threats in their environment.

To avoid being observed by potential predators, frogs can camouflage themselves.

The fact that some frogs are poisonous renders them unpalatable to animals that eat them for food.

Do Frogs Eat Frogs?

Yes, frogs do eat frogs, and this is also known as cannibalism. Some kinds of frogs do it more often than others.

For example, bullfrogs are known to eat their kind, especially when food is scarce.

There are a lot of reasons why frogs might eat other frogs.

One reason is that frogs are opportunistic feeders, which means they will eat whatever is around. If a frog sees another frog, it may just eat it as a food source.

The other reason for cannibalism is competition. If two frogs compete for the same resources, like food or territory, one may eat the other to eliminate the competition.

Lastly, cannibalism is another way for frogs to get the necessary nutrients. Frogs need a lot of protein to grow and breed, and other frogs are a good source of protein.

Cannibalism has been observed in various frog species, including the Cane toad, the Cape platanna, and the Blacksmith tree frog, among many others.

Frog Predators

Frog predators can be divided into different groups, such as bird predators, reptilian predators, mammalian predators, and amphibian predators which we will study one after the other.

Birds that eat frog


The heron species are one of the common predators that hunt frogs. Herons are large birds with long legs and necks.

Herons are efficient at catching frogs with their long beaks. 

Herons employ various methods of catching frogs.

One method is standing in the water and waiting for frogs to swim by. When a frog swims by, the heron strikes with its beak.

Herons often wade through shallow water, searching for frogs hidden in the mud or under vegetation. When a heron spots a frog, it strikes fast with its beak.


Kingfishers are known to prey upon frogs. To catch their prey, kingfishers use their long, pointed beaks. 

When hunting for frogs, kingfishers employ a wide range of strategies.

 One method is to wait for frogs to swim past while perched on a branch or rock over the water. The kingfisher will quickly swoop down and grab a frog out of the water.

Kingfishers also fly over water to look for frogs. When a kingfisher spots a frog, it won’t waste time plunging to the ground to get it in its beak.

Hawks and Owls

Both hawks and owls are classified as birds of prey, and each has unique characteristics that make it possible for them to hunt frogs successfully.

Hawks are able to capture and kill frogs due to their excellent eyesight and powerful claws, which they utilize to kill their prey.

Because of their superior night vision and hearing, owls can hunt frogs even when it is entirely dark outside.

Crows and Ravens

Crows and ravens are opportunistic feeders, meaning they will consume most things that come their way, including frogs.

However, they are not considered to be major predators of frogs.

Crows and ravens are known to consume frogs when the prey is readily accessible and not difficult to capture.

For instance, if a crow or raven spots a frog lying on a rock or swimming in a pond that is not very deep, it may decide to consume the frog.


Frogs are easy prey for egrets. Egrets are wading birds with long legs, necks, and beaks.

The egret is an expert predator of frogs and other aquatic creatures.

When hunting for frogs, egrets employ some strategies. Standing in the water and watching for passing frogs is one method.

The egret will quickly pounce with its beak when a frog swims by.

Reptiles that eat frogs


Snakes prey on frogs. Snakes are one of the most prevalent frog predators. Snakes are ambush predators, which means they wait for their prey to approach them.

They are also excellent at camouflaging themselves, making it difficult for frogs to notice them.

Some lizards are big enough to eat frogs whole, like monitor lizards and bearded dragons. Other lizards, like chameleons and geckos, might eat tadpoles or small frogs.

Lizards catch frogs in a lot of different ways.

One way is to catch frogs by surprise. Lizards often hide and wait for a frog to come close. When a frog gets close enough, the lizard will quickly strike and grab it in its mouth.

Lizards can also catch frogs by chasing them. Lizards can easily outrun frogs because they can move quickly.

When a lizard catches a frog, it usually kills it by biting it or squeezing it between its teeth.

Crocodiles and Alligators

Alligators and crocodiles prey on frogs. Both of these animals are the most common predators of frogs.  

As ambush predators, they wait for their prey rather than actively pursuing it.

They are also very good at camouflaging themselves, making it hard for frogs to spot them.

When a frog swims by, the crocodile or alligator will immediately leap out of the water and grab the frog in its mouth when it emerges from the water.

Crocodiles and alligators will also wander through areas of shallow water while searching for frogs hiding in the mud or beneath vegetation as another method for capturing their prey.

Mammals that eat frogs

Some mammalian species prey on frogs.


Raccoons are opportunistic eaters, and among their preferred foods are frogs.

Frogs high in trees or on branches are no match for a raccoon’s climbing prowess.


Skunks are another animal species that feeds primarily on frogs.

Skunks have an excellent sense of smell, allowing them to locate even frogs concealed in the grass or under leaves.


Frogs are a common food source for weasels, which are small, carnivorous mammals.

When it comes to catching frogs, weasels are lightning-fast and nimble.


Foxes are known to consume frogs as well. Since foxes are primarily nocturnal, they might search for frogs after dark.


Frogs are just one of many aquatic species that otters, which are mammals, devour. The otter’s swimming prowess makes it ideal for capturing aquatic prey like frogs.

Frogs are occasionally consumed by many mammals, including bears and coyotes.

Amphibians that eat frogs

There are certain species of amphibians that prey on frogs. The following are some examples:


Bullfrogs are huge, carnivorous frogs known to consume other species of frogs, including bullfrogs of a lower size.

Tiger salamanders: 

Tiger salamanders are a big species of salamanders known to consume frogs, tadpoles, and a variety of other small amphibians as part of their diet.

Cannibalistic frogs (frogs eating frogs)

Some species of frogs, such as the American green frog, southern bell frog, and the leopard frog, are known to consume their offspring, which is referred to as cannibalism.

Unusual Frog Predators


Several huge insects, such as dragonflies and praying mantises, feed on froglets and tadpoles when they are still young.

Fishy Feasts

When the opportunity presents itself, certain fish species, such as the northern pike, occasionally feast on frogs when available.

Humans eat Frogs

People eat frogs. Frog legs are considered a delicacy in several countries, including France, China, and Indonesia.

Frog legs are commonly served as an appetizer or side dish and can be prepared in several ways, including frying or roasting.

Some eateries serve frog legs in the United States’ southern regions. In addition to that, you may get them at grocery stores.

How do Frogs Defend Themselves from predators?

Frogs have evolved a wide range of defensive measures to protect themselves from potential threats.

These frog defense mechanisms consist of the following:


Frogs have the ability to camouflage themselves by blending in with their surroundings, making it more difficult for potential predators to spot them.

Some species of frog, for instance, have green skin, which enables them to blend in with the foliage and plants around them.


The fact that some frogs are poisonous makes them unappealing to animals that eat other animals for food.

Poison dart frogs, for instance, have brilliant colors that warn potential predators that they are toxic.


Frogs can quickly leap from one place to another, which helps them avoid being eaten by other animals.


Frogs can protect themselves from predators by hiding. They can do this in vegetation, behind rocks, or in water.


In order to surprise or frighten away potential predators, certain species of frogs produce loud noises.

Group behavior: 

Some species of frogs live in communities, which can be advantageous because it makes them less likely to be attacked by predators.

There is also the possibility that frogs will use a mix of these defensive systems to protect themselves from potential threats.

For instance, a frog might blend in with the foliage of a forest and then quickly hop away if it senses that a dangerous animal is approaching.

It’s also possible for a frog to create a loud noise to scare off a potential enemy and then quickly hop away.


Now we know what eats frogs, and even though they are so appealing and possesses different defense mechanism for protecting themselves against amphibian predators, frogs still have to worry about being eaten by wildlife that feeds on frogs.

Although frogs are difficult to catch, many natural frog predators have figured out how to catch and kill them.

Frogs are a common food source for various animals, including reptiles, amphibians, fish, mammals, birds, turtles, alligators, and humans.

Frogs have a few defense mechanisms, but the best approach to avoid being eaten is to hide and run away.
