Frog and Toad Difference and Explanation

To learn about the difference between frogs and toads, let’s get introduced to both the animals. Frog and Toad are members of the carnivorous group of animals that belong to the amphibians category of vertebrates. They need water and a moist environment to survive and can also breathe and absorb water through their thin skin. Being amphibians, they have dual home, land, and water and comprise special glands that can produce useful proteins. Some other animals that are amphibians include salamanders, blindworms and newts. 

 

What is a Frog?

A frog is an amphibian from the large carnivorous group of animals and it is tailless and short-bodied. Frogs can be found in the regions of the tropics to the subarctic and the maximum can be found in the tropical rainforest. Warty frogs are termed as toads. Therefore, it’s said that all toads are frogs whereas all frogs are not toads. 

 

We will further discuss the difference between frog and toad in more detail in this article. An adult frog has a stout body with protruding eyes and limbs are folded underneath. They have anteriorly attached tongue and glandular skin. The secretions from the skin may be toxic and distasteful. Adult frogs do live in freshwater and dry land and some of them are adapted to live underground or terrestrial.

Frog Characteristics

Frogs are animals that are closely associated with water and a very humid environment. There are ectodermal glands throughout the body in a particular layer of frog skin. In some cases, these glands secrete poison. Usually, the parotid gland is behind the eye. The venom gland does not always work by contact, but most of the time it works when a threat is felt. Certain species of frogs are one of the most toxic animals on the planet. The frog also has an adhesive gland on the sucker of the finger. They use this to scale different surfaces. Frogs have lungs that they use to take up oxygen, but they can also take it through the membranes of the skin. 


Generally, the skin of a frog is smooth and always moist. Your limbs are generally long and slender, and your body is not very sturdy. There are exceptions to these general rules. They can come in different colors and often the brightest ones are the most toxic, and recently the first bioluminescent frogs were discovered. 


What is a Toad?

A toad is an amphibian animal from the family Bufonidae which has dry and leathery skin with short legs and bumps (also called warts) that cover parotoid glands. Besides the family Bufonidae, it also belongs to families Calyptocephalella, Bombinatoridae, Myobatrachidae, Microhylidae, Rhinophrynidae, and Scaphiopodidae. 

 

Compared to frogs, a toad is found in terrestrial habitats and has drier and rougher skin. Toads are known to travel to all areas of the ponds and lakes including breeding and non-breeding areas. They do not mate with close kin and females recognize the kins by the difference in male vocalizations. A toad also belongs to the same order Anura (tailless) as that of a frog.

Toad Characteristics 

Toads are generally less dependent on bodies of water than frogs because of their rough skin and hundreds of warts.  They prefer muddy areas but they can live in ponds and lagoons as well where they can dig into the terrain and protect themselves from dryness. This is especially important during the dry and drought seasons. 


Also, toads can be spurred. These are hind leg ridges that help you set them up better when jumping or holding the females during mating. Toads are generally considered to be more terrestrial. They usually hop around, but they also use all their four limbs as well. Arboreal frogs are often considered real frogs.


What is the Difference Between a Frog and a Toad?

We have put a frog and toad difference below in a tabular form according to their characteristics. It will help you to easily identify toads vs frogs next time you find them in front of your eyes.

Characteristics

Frog

Toad

Skin texture

Frogs have smooth, slippery, and moist skin.

Toads have rougher, drier, and patchy skin composed of warts or hard bumps.

Appearance

Frogs are seen to be lean and slender in appearance.

Toads are shorter but bulkier than frogs.

Locomotion

Frogs rarely crawl.

Toads are found crawling and this is how they do the movement from one place to another.

Laying Eggs

Frogs lay eggs in clusters.

Toads lay eggs in long chains.

Habitat

Frogs are found in nearby water their whole lives.

Toads are very much adapted to living on terrestrial or land areas.

Feet

Frogs have webbed feet that help them to live in semi-aquatic areas.

Toads do not possess webbed feet.

Legs

Frogs are found jumping higher due to their long legs.

Toads have shorter legs and as compared to frogs, they cannot jump or leap so high.

Lifespan

The lifespan of frogs may vary from up to 16 years; the oldest frogs are found to live up to 21 years.

Their life span is 10-15 years; a common toad called Bufo bufo is found to have lived up to 40 years.

Length and Width

The length of a frog is found to be 6-9 cm and varies according to the varieties.

Their length is 10 to 13 cm or 5-6 inches and their width is 7 cm.

Colour

The skin of a frog varies as there are 3000 different species found; the most common colour is leafy green and muddy brown.

Toads are of different colours; their back is greyish black and their belly is yellowish-grey.

Toxicity

Some frogs are highly poisonous; golden poison frogs are the most poisonous that can kill 10 men. 

Cane toads are toxic as their toxins can kill cats and dogs.

Life in Colder regions

40 million years ago when the climate was warmer, frogs could be found in Antarctic regions.

They are less found in Antarctic regions.

Increased Size

A frog can look bloated sometimes.

A horrified toad swells up to a bigger size when it finds its predator.

Tadpoles

The tadpoles of frogs are slimmer and golden in appearance.

The tadpoles of toads are black and chunky in appearance.

 

Tadpoles

We just found out how the tadpoles of frogs and toads differ in their appearance. Let’s learn more about tadpoles. Frogs and toads reproduce by laying eggs and these eggs are hatched to form aquatic larvae known as tadpoles. Tadpoles have internal gills and tails with highly specialized mouthparts. They later metamorphose into adults and the life cycle is completed. A tadpole is also called a pollywog and is fully aquatic, however, rare tadpoles of a few amphibians can be terrestrial.


Conclusion

Understand what frogs and toads are and then focus on their differences. Follow the tabulated form of this difference between these two animals. Refer to clear images of these animals to understand their differences well.

FAQs on Difference Between Frog and Toad

1. Is a Frog Poisonous?

Yes, some frogs like ‘golden poison frogs’ are highly toxic and can kill up to 10 men with their poison. Certain species of frogs are very toxic. Frogs have ectodermal glands throughout the body in a particular layer of frog skin. In some cases, these glands secrete poison. The venom gland does not always work by contact, but most of the time it works when a threat is felt.

2. Are Frogs and Toads alike?

All toads are actually frogs, but not all frogs are toads. Because toads are part of the frog family and share some of the same characteristics as frogs. Toads are very different from frogs. Like a frog, the toad has evolved as it did because of the environment in which it lives.  

3. Describe the difference between a frog and a toad based on their appearance.

One of the main differences is that toads tend to be thick, stout-looking animals, very stubby, shorter than a frog but very muscular. In contrast, frogs are thinner, leaner, slender, and finer.  

4. Explain the similarities between a Frog and a Toad.

Even though there are major differences between a frog and a toad, there are many similarities as well, such as- 

  • They are both amphibians.

  • They both hatch from eggs. 

  • They both have lungs, brain, and heart.

  • Both the young ones live in water.
