Difference between frog and toad
Frog vs toad:
Frogs and toads are similar in so many ways that it may be quite difficult to tell them apart at times. Although they are both known as amphibians and they both start their lives as tadpoles, certain differences in their appearance to more subtle characteristics such as their biological make as well as their behavior prove to be useful I telling these two creatures apart.
What is a frog?
Frogs belong to the order of Anura, which translates in to “tailless” and they are characterized by a short body, webbed toes and fingers, protruding eyes, bifid tongue and the absence of a tail. The long powerful legs of a frog are specifically thus designed to improve their jumping performance as frogs are essentially known as jumpers. Frogs are semi aquatic and lay their eggs in water, typically in ponds, lakes or puddles which eventually develop in to tadpoles that possess tails and gills and are capable of living in water. Frogs are found in both tropics and subarctic regions and over 5,000 species have been discovered so far of which the number is decreasing significantly.
What is a toad?
Toads are characteristic of their dry leathery skin short legs and snout-like parotoid glands which are often mistaken for warts. However, contrary to the popular belief that humans develop warts by toads coming in contact with human skin, it is merely a myth. The wart like glands on their skin merely enables them to blend in with the environment, thus misleading predators. Toads spread across a whole range of families such as Bufonidae, Bombinatoridae, Discoglossidae, Pelobatidae, Rhinophrynidae, Scaphiopodidae and Microhylidae.
What is the difference between a toad and a frog?
The difference between a frog and a toad can be recognized, first and foremost from their eggs. Frog eggs will be speckled and lighter in color while toad eggs will generally be much smaller in size as well as be black in color. And although both the eggs hatch in to tadpoles, it can be observed when they are about one month old that frog tadpoles have teeth whereas toad tadpoles normally do not grow teeth. After about nine weeks, one can clearly identify the frog tadpole from a toad tadpole as they start developing their unique characteristics at this age.
The frog will have a smooth, moist skin whereas a toad will typically have rough drier skin which will be quite scaly in nature with protrusions on the skin that look like warts. Also, the size and nature of their bodies vary greatly as frogs normally tend to have shorter, narrower bodies whereas toads have broader, flatter bodies. Also, frogs have longer legs that are specifically made for leaping which are also webbed that come in handy when it comes to swimming. Toads have relatively shorter legs and they normally walk rather than leap. When comparing the nature of eyes of the two species, frogs have bulging eyes whereas the eyes of a toad are quite withdrawn in to the head.
Frogs are rarely considered as poisonous although there are certain species of frogs that do contain a certain amount of poison in them. With regards to this aspect, toads are the notorious creatures that are believed to possess bags of poison behind their eyes. They are usually considered as poisonous to the touch. Frogs can live both in water and on land near water whereas toads only breed in water and live mainly on land.
