Differences between frogs and toads
Although it is true that they share a similar aspect, there are a series of divergences at the physical, reproductive or customs level; for example, frogs are great leapers, while toads are great burrowers

At first glance they seem the same, although there are differences between frogs and toads (just above these lines). The first of them begins with the size and its shape, and continues with the colors, texture and sounds. A detailed observation will indicate many details to those who wish to identify the differences between frogs and toads.
They both come from the same family of amphibians. They are batrachians classified as anurans; i.e. specimens without a tail. Nevertheless, frogs belong to the genus Rana, while toads belong to the Bufo. Jesters are large frogs with thick, corrugated fur, unlike frog.
Frogs and toads share a similar evolutionary process; both start as tadpoles and lose their tails when completing the metamorphosis process. Now, their customs and their habitat begin to demarcate the differences between the two.
What are the differences between frogs and toads?
- Frogs are more stylized specimens, with a shiny and slimy appearance, with a predominance of a single colour. On the other hand, toads have wrinkled, thick and usually spotted skin.
Although in appearance they can easily be differentiated, there are types of frog whose physical characteristics resemble the toad. Although they remain stylized, the colors are more similar to those that identify toads.
The same thing happens in reverse. There are species of toads much thinner than the most common, whose skins are smoother. However, they may feel rough and thick to the touch like a common toad.
- Morphology. Toads are chunky, coarse and fat amphibians, and they have sturdy limbs and a large head. Their legs are usually short and lack a membrane between their toes, since they do not swim.
Conversely, the frogs are slim and stylized, and are characterized by having long legs for long-distance jumps. Between their fingers they have an interdigital membrane, characteristic of aquatic amphibians.
- Physiognomy. Frogs have rounded eyes and horizontal pupils, while toads' eyes are usually slanted and have a vertical pupil. In toads their eardrum is almost imperceptible, being the opposite in frogs.
In both cases, these amphibians use their protractile tongue to reach their food. However, unlike toads, frogs have teeth in the upper jaw.
Customs of frogs and toads
Frogs are by nature amphibians that inhabit both water and land. They can be seen swimming underwater or jumping on it, taking advantage of the leaves that are floating. They are the anurans with the largest population in the world, so there are very diverse species.
Toads are par excellence terrestrial and burrowing; their hind legs are not as developed because they do not require greater agility to jump. Instead, they travel over the land for short distances, but can sometimes be fast.
In both frogs and toads, there are specimens capable of producing toxins toxic to other animals. These can cause poisoning and death just by touching your skin; this effect can be just as harmful to man.
Reproduction of frogs and toads
Another condition that makes the difference between frogs and toads is the way they reproduce. Although both are egg layers, the way to do it is different.
In toads the habit of living on the ground is interrupted to lay their eggs; places them in the form of cords or chains, close to leaves and very quickly, and then hibernate again.
In the case of frogs, they lay their eggs in the water like bunches of grapes. Between them they have a substance that holds them together; a female frog has the capacity to lay between 1,000 and 2,000 eggs.
A characteristic condition of toads is the change of sex. This type of amphibian has an organ called the bidder that is located in their testicles. Only in case the testicles are removed, the bidder organ will transform into a kind of ovary. With this, an optimal production of ovules will be possible to guarantee their reproduction.
