Toads and frogs are both amphibians that belong to the order Anura, which means “tailless” in Greek. While they share many similarities, there are some key differences between the two. One of the most noticeable differences is their appearance. Toads tend to have dry, warty skin and a stocky build, while frogs have smooth, moist skin and a slender build.
Another difference between toads and frogs is their habitat and behavior. Toads are typically found on land and prefer drier environments, while frogs are found near water and require moist environments to survive. Frogs are also known for their jumping ability and are often seen leaping from place to place, while toads tend to move more slowly and rely on camouflage to avoid predators.
Despite their differences, toads and frogs play important roles in their ecosystems. They both consume insects and other small invertebrates, and are in turn preyed upon by larger animals. Understanding the differences between these two amphibians can help us appreciate the diversity of life on our planet.

Frog vs Toad
Frogs and toads are both amphibians, which means they are cold-blooded vertebrates that spend part of their lives in water and part on land. They have similar body shapes, but there are some key differences between the two.
One of the most noticeable differences is their skin. Frogs have smooth, moist skin, while toads have dry, bumpy skin. This bumpy skin helps toads retain moisture and stay hydrated, even in dry environments.
Another difference is their habitat. Frogs prefer to live near bodies of water, while toads are more adaptable and can live in a variety of environments, including deserts and forests.
In terms of classification, both frogs and toads belong to the order Anura, which means “tailless” in Greek. This distinguishes them from other amphibians, such as salamanders, which have tails.
Physical Differences
Toads and frogs may look similar at first glance, but upon closer inspection, there are several physical differences that set them apart. This section will explore the various physical differences between the two amphibians, including skin texture, body structure, eye structure, and teeth structure.
Skin Texture
One of the most noticeable differences between toads and frogs is their skin texture. Toads have dry, bumpy, and warty skin that is not very smooth to the touch. In contrast, frogs have moist, smooth, and sometimes slimy skin that is much smoother than that of a toad. Both toads and frogs have waterproof skin that helps them retain moisture and stay hydrated.
Body Structure
Toads and frogs also differ in their body structure. Toads have shorter hind legs and a dumpy body shape that makes them look less athletic than frogs. Frogs, on the other hand, have longer hind legs and a more athletic-looking body shape that allows them to jump farther and faster than toads.
Eye Structure
Another physical difference between toads and frogs is their eye structure. Toads have round pupils and a more horizontal eye orientation, while frogs have vertical pupils and a more circular eye orientation. This difference in eye structure helps frogs see better in low-light conditions, while toads are better adapted to seeing in bright daylight.
Teeth Structure
Finally, toads and frogs also differ in their teeth structure. Both amphibians have vomerine teeth, which are small teeth located in the roof of their mouths. However, toads have fewer vomerine teeth than frogs, and their teeth are less developed. This difference in teeth structure reflects the different diets of toads and frogs, with toads primarily eating insects and other small invertebrates, while frogs also eat larger prey like mice and small birds.
Behavioral Differences
Toads and frogs have different ways of moving. Frogs are known for their ability to hop, while toads tend to walk or crawl. Frogs can also leap long distances, while toads have a shorter range of movement.
Habitat Preferences
Frogs are typically found near water, while toads tend to live on land. Frogs prefer wet environments, such as ponds, lakes, and streams, while toads can be found in a variety of habitats, including woods and fields.
Feeding Habits
Frogs and toads have different feeding habits. Frogs tend to eat insects, such as crickets and flies, as well as small worms. Toads, on the other hand, have a more varied diet that includes insects, snails, grubs, and slugs.
Toads also have a unique feeding mechanism. They have sticky tongues that they use to catch their prey. This allows them to catch insects and other small creatures quickly and efficiently.
Reproduction Differences
Toads and frogs have different methods of egg laying. Frogs lay their eggs in clusters, while toads lay their eggs in long lines. Frog eggs are generally laid in water, while toad spawn can be found in water or on land. The eggs of both species are covered in a jelly-like substance that protects them from predators.
Development of Offspring
After the eggs are laid, the development of the offspring differs between toads and frogs. Frog eggs hatch into tadpoles, which are aquatic and have gills for breathing. The tadpoles will eventually develop legs and lungs, and move onto land as adult frogs.
Toad spawn also hatches into tadpoles, but toad tadpoles are more likely to develop into terrestrial juveniles with lungs before they develop legs. Toad tadpoles are also known to be more aggressive and cannibalistic than frog tadpoles.
In some cases, toads may give birth to live young instead of laying eggs. The young are fully formed and can move independently at birth. Frog species do not give birth to live young.
Species Specific Information
True toads are members of the Bufonidae family, which includes over 500 species of toads. These toads are characterized by their dry, bumpy skin and their parotoid glands, which produce toxins to deter predators. One well-known species of true toad is the cane toad, which is native to South and Central America but has been introduced to other parts of the world, causing harm to local ecosystems.
True Frogs
True frogs belong to the Ranidae family, which includes over 800 species of frogs. These frogs have smooth, moist skin and long, powerful legs for jumping. Some species of true frogs, such as tree frogs, are known for their ability to climb and stick to surfaces.
Unique Species
There are also several unique species of toads and frogs that have their own distinct characteristics. For example, the golden poison frog, found in Colombia, is one of the most toxic animals in the world. Its skin contains enough poison to kill 10 humans. The American toad, found in North America, is known for its distinctive call, which sounds like a long trill.
In general, toads and frogs have adapted to their environments in different ways. Toads tend to have drier skin and are better adapted to living on land, while frogs have moist skin and are better adapted to living in water. However, there is a lot of variation within each group, and some species of toads are excellent swimmers, while some species of frogs are better adapted to living on land.
Role in Ecosystem
Both toads and frogs play an important role in their respective ecosystems. They are both predators and prey, and their presence can indicate the health of an ecosystem.
Toads and frogs feed on insects, worms, and other small invertebrates, which helps to control their populations. They also serve as prey for larger animals such as birds, snakes, and fish.
In addition to their role in the food chain, toads and frogs also help to maintain a healthy environment. They consume pests that can damage crops and gardens, and they can help to control the spread of diseases like West Nile virus and malaria by feeding on mosquitoes.
Toads and frogs are also important indicators of the health of an ecosystem. They are sensitive to changes in their environment, and their presence or absence can signal problems like pollution or habitat destruction.
In Canada, organizations like Wildlife Preservation Canada work to protect the habitats of toads and frogs. By preserving wetlands and other natural areas, they help to ensure that these important species can continue to play their vital role in the ecosystem.
