Frogs are amazing amphibians that have mastered living in both water and on land. Their unique bodies allow them to jump, walk, and swim. But can all frogs swim? If you want a quick answer: Most frogs are able to swim, though some species are better swimmers than others.

In this comprehensive article, we’ll take an in-depth look at frog swimming abilities. We’ll discuss the frog body parts that enable swimming, look at differences between frog species, and outline which types of frogs are skilled swimmers versus poor swimmers.

Anatomy That Allows Frogs to Swim

Webbed Hind Feet

One of the most important anatomical features that enable frogs to be strong swimmers are their webbed hind feet. The webbing between a frog’s toes on their powerful hind legs creates broad flipper-like feet that provide tremendous propulsion in water.

When a frog kicks its webbed hind feet in unison, it generates forward thrust that propels the streamlined amphibian through the water.

Interestingly, not all frogs have the same amount of webbing. Aquatic species like the African clawed frog tend to have more extensive webbing extending all the way to the ends of their toes. In comparison, tree frogs have smaller pads of webbing suited for clinging to branches, not powered swimming.

Streamlined Body Shape

A frog’s streamlined body shape also contributes to its ability to swim. A smooth, slippery profile with a rounded head and tapered rear reduces drag and allows a frog to glide gracefully through the water with ease.

This hydrodynamic silhouette paired with powerful thrust from their hind legs enables certain species to achieve impressive speeds – Australian rocket frogs can swim at 1.6 meters per second!

Additionally, many aquatic frogs have laterally flattened bodies that function like miniature scuba fins, providing increased surface area for even greater propulsion. Species like the African clawed frog use vertical undulations of their dorsoventrally flattened figures to generate wave-like movements that thrust them smoothly through the water.

Strong Hind Legs for Propulsion

Robust, muscular hind legs are critical for providing the driving force behind a frog’s swimming kick. Equipped with strong thigh, calf and foot muscles built for jumping on land, a frog is able to utilize similar leg extensions for effective water propulsion.

In fact, research shows that semi-aquatic frogs like green frogs, bullfrogs and leopard frogs have significantly larger hind limb muscles compared to terrestrial tree frogs. While all frogs are capable short-distance swimmers, these brawny back legs give aquatic species unmatched speed and stamina in the water.

Frog Species Max Swim Speed
Australian Rocket Frog 1.6 m/sec
African Clawed Frog 1.2 m/sec
Northern Leopard Frog 0.8 m/sec

So whether escaping predators, hunting for food or migrating to breeding ponds, frogs rely on adaptations like webbed feet, hydrodynamic body shapes and powerful hind legs to access their world of watery wonder.

Their exceptional swimming skills enable these athletic amphibians to thrive in aquatic habitats across the globe!

Frog Species with Superior Swimming Abilities

African Dwarf Frogs

The African dwarf frog is one of the best swimmers among all frog species. Native to the tropical forests and rivers of central Africa, these petite amphibians have fully webbed feet and hands that propel them smoothly through the water.

They can stay submerged for up to 5 hours, aided by their small size and slow metabolism. African dwarf frogs are a popular exotic pet due to their friendly nature and aquatic talents.

Pig Frog

The aptly named pig frog inhabits swamps and ponds across the southeastern United States. These rotund amphibians have partly webbed hind feet and loose skin folds traveling along their sides and legs which are believed to aid in gliding through the water.

Pig frogs can remain beneath the surface for over 30 minutes without needing air. Their superior swimming skills allow them to evade predators and hunt aquatic prey with ease.

Pickerel Frog

Found throughout the northeastern U.S. and eastern Canada, pickerel frogs frequent cold streams and spring-fed pools. They possess long hind legs with extensive webbing that propel them through the chilly water. Pickerel frogs can stay submerged at length while foraging the bottom sediments for food.

These hardy swimmers even hibernate underwater during the winter by burying themselves in mud while holding their breath for up to 4 months!

Green Frog

Common across North America, the green frog thrives in any permanent body of fresh water. Possessing long hind legs and feet with moderate webbing, they are agile swimmers able to swiftly dart after flying insects that land on the water’s surface.

Green frogs will also dive down several feet to reach underwater food or escape predators. While not the most hydrodynamic, they rank as one of the continent’s most widespread and successful frog species.


The iconic bullfrog is perhaps the ultimate amphibious predator, using its powerful hindquarters and extensively webbed feet to chase prey while swimming or pounce up to 6 feet from shore! They inhabit lakes, rivers, marshes and ponds across North America.

Underwater, bullfrogs can breath hold up to 6 hours by slowing their heart rate. Their supreme aquatic adaptations and large size make bullfrogs the foremost frog swimmers on the continent.

Frog Species That Struggle With Swimming

Tomato Frog

The tomato frog (Dyscophus antongilii) is a small, terrestrial frog native to Madagascar. Reaching only 2-3 inches in length, these little amphibians have short legs and a plump body shape not suited for swimming (Spruce Pets).

They got their name from their round, red-orange color resembling a tomato. Tomato frogs prefer to hop around the forest floor rather than taking a dip. When faced with water, they would likely sink from their dense build and lack of webbed feet.

Poison Dart Frog

Poison dart frogs like the blue poison frog (Dendrobates azureus) are vibrantly colored frogs measuring 1-2 inches long. They live in the rainforests of Central and South America. While poison dart frogs love moisture, most species avoid bodies of water since they possess no real adaptations for swimming (Earth’s Birthday).

Their tiny size and lack of webbed appendages make them poor swimmers. Additionally, the toxin excreted through their skin that makes them poisonous can be washed away in water.

Pacman Frog

The Pacman frog (Ceratophrys ornata) is another semi-aquatic species unfit for swimming. Native to South America, these predators can grow over 5 inches long and have enormous mouths spanning nearly the width of their giant heads. They lay in wait to ambush prey rather than chasing it down.

Pacman frogs tend to sink when placed in deep water as their dense bodies lack buoyancy. They may paddle around a bit by kicking, but certainly cannot swim after food (The Spruce Pets).

Desert Rain Frog

The desert rain frog (Breviceps macrops) is the smallest frog in southern Africa, reaching just over 1 inch long. As its name suggests, this species dwells in arid desert habitats. Desert rain frogs have a flat body and long hind legs suited for burrowing through sand.

When rainfall hits their desert homes infrequently, these tiny frogs emerge out of hiding. However, the pools of water that form are likely too large and deep for the tiny creatures to navigate through swimming (Earth’s Birthday).

Red-eyed Tree Frog

Can climb smooth surfaces Yes
Possesses webbed feet No
Body length 2 inches

The vibrant green red-eyed tree frog (Agalychnis callidryas) is a well-known rainforest amphibian. While they live high up in trees near freshwater ponds and streams, their toe pads allow them to grip branches without webbed feet for swimming. Their small size wouldn’t carry them far either.

So while moisture is essential to their arboreal habitat, red-eyed tree frogs would likely sink if they fell into a pond below!

Why Do Some Frogs Swim Better Than Others?

Not all frogs are created equal when it comes to swimming abilities. Several key physiological factors determine how well a frog can propel itself through water and stay afloat, including:

Leg and Foot Structure

Frogs with long, muscular hind legs and fully webbed feet (where the toes are connected by skin) tend to be the best swimmers. The webbing aids with propulsion and prevents water resistance between the toes, while strong kicks from extended hind legs provide powerful forward thrusts.

Tree frogs and other frogs that dwell mostly on land usually have smaller legs and little to no webbing between their toes. Without those aquatic adaptations, their swimming ability is limited.

Body Size and Shape

A frog’s body proportions also affect its time in the water. Streamlined, smooth-skinned frogs with flat heads and slim torsos can glide through water more easily than bulky, rough-skinned varieties. Their hydrodynamic shapes mean less drag and energy required for swimming.

Additionally, smaller frogs have a higher surface area relative to their volume. This gives them more contact with the water to generate propulsion. Larger, heavier frogs may struggle to stay afloat and quickly become fatigued from swimming.

Natural Habitat

Frogs that live mostly in the water (aquatic habitat) unsurprisingly tend to be better swimmers than terrestrial and arboreal (tree-dwelling) frogs. Species like the African clawed frog and North American bullfrog have adaptations for their amphibious lifestyle, including webbed toes and powerful kicks.

Meanwhile, frogs not normally found around ponds and streams haven’t evolved features for frequent swimming. Red-eyed tree frogs in rainforests rarely descend from high branches, so proficient swimming isn’t essential to their survival.

In short, a frog’s swimming prowess depends greatly on its leg structure, size, shape, and natural habitat. Next time you see a frog, look for these clues to guess how comfortable it might be taking a dip!



As we’ve explored, most frogs are able to swim to some degree, thanks to adaptations like webbed feet and strong hind legs. However, some species like African dwarf frogs and bullfrogs excel at swimming, while others like tomato frogs struggle.

A frog’s swimming ability is influenced by leg and foot structure, body size and shape, and the habitat they naturally live in. Understanding the amazing diversity of frogs helps shed light on why some readily take to the water while others prefer to stay on land.
