Frog vs toad: how to tell them apart (and why all toads are frogs)

A wet spring night. Something squat and brown crawls across a garden path, then another creature leaps into the pond with a splash. Frog, toad, or both?

Frog vs toad is a trick question, because all toads are frogs. “Toad” is the everyday name for frogs with dry, warty skin, short legs for walking and big poison glands behind the eyes. “Frog” usually means the smooth, moist-skinned jumpers that live near water. Scientists only treat one family, the true toads (Bufonidae), as toads. Here is how to tell them apart in seconds, plus the edge cases.

What is the difference between a frog and a toad?

Toads are a kind of frog. Most frogs have smooth, moist skin and long back legs for leaping, and live close to water. Toads usually have drier, warty skin, shorter legs for walking, a stouter body and large poison glands behind the eyes, and many live in drier places. These are rules of thumb with exceptions, not strict scientific groups.

Are toads frogs?

Yes. “There is no scientific distinction between ‘frogs’ and ‘toads,'” says Animal Diversity Web. Every toad belongs to the frog order, Anura. The Burke Museum puts it simply: all toads are frogs, but not all frogs are toads. Only one family, Bufonidae, is known as the “true toads.”

The numbers show how small that family is. AmphibiaWeb lists 8,060 frog species and 667 true toads (counts on 14 October 2026), so only about 1 frog species in 12 is a true toad (our calculation: 8,060 ÷ 667 ≈ 12).

“Toad” is used far beyond the true toads. Hundreds of frogs in 14 families are called toads or “toadlets,” wrote herpetologist Jodi Rowley for the Australian Museum. The fire-bellied toads and spadefoot toads, for example, sit in their own families (AmphibiaWeb). And it works the other way: some true toads, such as the harlequin toads (Atelopus), look nothing like the warty brown toad of storybooks. Rowley notes that while many true toads have bumpy brown skin, “others are smooth-skinned and brightly coloured.”

Is a toad an amphibian?

Yes. Toads, like all frogs, are amphibians: animals with thin skin that usually start life in water as tadpoles and later move onto land. AmphibiaWeb counts 9,141 amphibian species in total, and frogs and toads make up the large majority. You can browse more amphibians in our animal index.

How can you tell a frog from a toad?

Look at the skin, the legs and the head. Frogs have smooth, slimy skin and long back legs built for leaping. Toads have dry, warty skin, shorter back legs and a rounder body, and they tend to crawl rather than hop. Toads also have large bulging glands behind their eyes. Check several clues together, because single features overlap.

Frogs have “long legs for jumping away quickly,” says Froglife, while common toads “tend to crawl rather than hop” (Froglife). Toads usually have “drier, bumpier ‘warty’ skin and prefer drier habitats,” says the Burke Museum. These body shapes are structural adaptations; see the adaptations of a frog for how skin breathing and powerful legs work.

Spot the difference. Tap each clue to check your answer.

Clue 1: Its skin looks wet and shiny, and it vanishes into the pond in one big leap.

Frog. Smooth, moist skin and long jumping legs are classic frog features.

Clue 2: It has two big, swollen bumps just behind its eyes.

Toad. Those are parotoid glands, which hold toxin. Some frogs and salamanders have them too, but they are most obvious on toads.

Clue 3: In the pond you find long strings of jelly with a double row of black dots.

Toad spawn. Common toads lay “long jelly-like strings of spawn” with a double row of eggs, says Froglife.

Clue 4: It is brightly coloured and smooth-skinned, but it is in the true toad family.

A harlequin toad (Atelopus). Proof that looks alone can fool you.

What are the bumps behind a toad’s eyes?

They are parotoid glands, poison glands found behind the eyes on toads and some frogs and salamanders. In toads they hold bufotoxin, a toxin that attacks the nerves. It makes toads taste bad and can harm predators that bite them. The smaller bumps on a toad’s back are skin glands, not warts.

The Burke Museum calls them “parotid glands” and says that “in toads, these glands contain bufotoxin, which is a neurotoxin.” Common toads “produce a toxin from their skin, which makes them distasteful to predators,” says Froglife. Bright frogs use the same chemical defence in a more extreme way; see how poison dart frogs stay toxic. Warning through bad taste turns up across the animal world, as in monarch and viceroy butterflies.

How are frog eggs and toad eggs different?

Frogs lay their eggs in clumps; toads lay them in strings. Common frog spawn sits in jelly clumps in shallow ponds, while common toads wrap their eggs in long jelly strings, with a double row of eggs, in deeper water. Many true toads around the world lay eggs in strands rather than clumps.

Spawn is the easiest clue in spring. “Frog spawn is laid in gooey clumps whereas toad spawn are long strings,” says the Herts and Middlesex Wildlife Trust. The same pattern holds for many true toads worldwide, which “lay their eggs in long strands instead of clumps,” says the Australian Museum. One cane toad clutch can hold up to 35,000 eggs, says the Queensland Government.

Where do frogs and toads live?

Frogs usually stay close to water, while many toads wander into drier places such as woodland, scrub and grassland. Both need water to breed. In Britain, common frogs breed in shallow water such as ponds and even puddles, while common toads prefer deeper ponds and lakes and return to the same ancestral ponds along the same routes each year.

Those habits come from Froglife. True toads are native to every continent except Antarctica and Australia, says the Australian Museum. Toad migrations to the same pond every spring are a behavioural adaptation; learn more in animal adaptations explained.

Can you get warts from touching a toad?

No. Warts are caused by human papillomavirus (HPV), a human virus, and no amphibian can give you one. The bumps on a toad’s skin are glands, not warts, and they don’t make anything that causes warts. Toads can carry germs such as salmonella, though, so wash your hands after touching any frog or toad.

“There are no amphibians that give you warts,” says the Burke Museum. The Mayo Clinic explains that warts come from human papillomavirus, as summarised by the Forest Preserve District of Will County, which also passes on the CDC’s advice to wash your hands thoroughly after handling a reptile or amphibian. Never lick or kiss a frog or toad: their skin can carry salmonella and toxins.

Are toads poisonous to dogs?

Some are. In the US, the cane or marine toad (Rhinella marina) and the Colorado River toad (Incilius alvarius) can seriously poison or kill dogs that bite or mouth them. Most smaller toads cause milder signs, such as drooling and vomiting. If your dog mouths a toad, rinse its mouth with plenty of water and call a vet straight away.

The Merck Veterinary Manual (reviewed July 2026) calls the marine toad “the most toxic species of toad in the US.” It is an introduced species established in Florida, Hawaii and Texas, and the Colorado River toad lives in the south-western US and northern Mexico. Signs include heavy drooling, retching, vomiting, weakness, breathing trouble and seizures, and heart rhythm problems in severe cases. The manual advises that the mouth “should be immediately and thoroughly lavaged with copious amounts of water,” and warns against making the animal vomit.

This is first aid, not a cure. A dog that has mouthed a cane toad needs a vet as fast as possible. In Australia, where cane toads were released in 1935 to control farm pests, the Queensland Government warns they “can harm domestic animals if eaten.”

Why do frogs and toads matter in their ecosystems?

Frogs and toads are middle links in food webs. Adults eat insects, slugs, worms and other small animals, and in turn feed snakes, birds, raccoons, turtles and fish. Because amphibians are among the first animals affected when conditions change, scientists treat them as indicator species, early warnings that an ecosystem is in trouble.

Frogs: common frogs eat “insects, slugs and worms” (Froglife), and their predators include “snakes, birds, raccoons, turtles, fish,” says the Burke Museum, which calls amphibians “a key indicator species.”

Toads: common toads eat invertebrates “and even small vertebrates,” says Froglife, and their toxins protect them from many predators. Toad tadpoles are also “unpalatable to fish, unlike their froggy relatives,” says the Herts and Middlesex Wildlife Trust, which gives toads an advantage in ponds with fish.

The ripple effect: two real stories show what happens when the frog community changes. A fungal disease, chytridiomycosis, has contributed to the decline of at least 501 amphibian species and about 90 presumed extinctions over the past half-century, with frogs hit hardest, according to a 2019 study in Science by Ben Scheele and colleagues; some scientists later questioned how the totals were estimated. Among the hardest hit are the 131 harlequin toads, true toads of Central and South America; none has improved its status since 2004, reported Lötters and colleagues in 2023. And in Australia, where cane toads were introduced, their toxic skin “can kill native predators” that eat them, says the Queensland Government. Another amphibian in trouble is the axolotl; see why axolotls are endangered.

How you can help: build a wildlife pond without fish, avoid garden pesticides, help toads cross roads on spring migration nights through local “toad patrols,” and never move frogs, toads or spawn between ponds, which can spread disease.

Myths about frogs and toads

Myth: Touching a toad gives you warts.

Fact: Warts are caused by human papillomavirus. No amphibian gives you warts. Why people believe it: a toad’s bumpy skin looks like it is covered in warts. Source: Burke Museum; Mayo Clinic via Forest Preserve District of Will County.

Myth: Toads and frogs are two different kinds of animal.

Fact: All toads are frogs. “Toad” is a common name, and only the family Bufonidae are true toads. Why people believe it: in Europe and North America, local toads and frogs look very different. Source: Animal Diversity Web; Burke Museum.

Myth: Any warty brown “toad” in Australia is a cane toad, so it is fine to kill it.

Fact: Many native Australian frogs, such as toadlets, are bumpy and brown but are not cane toads. Killing them by mistake harms native wildlife. Why people believe it: the cane toad is the only true toad in Australia, so people assume every toad-like animal is one. Source: Australian Museum.
