Answer :
Frogs have four feet - 2 front feet and 2 back feet. Each front foot contains 4 digits and each back foot contains 5 digits.Humans have 5 digits in each limb and there is no webbing like frog.
The back foot is webbed which helps them paddle in water and thus make swimming smooth and efficient . Webbing of foot increases surface area, so when it pushes water backwards due to larger surface area, frog can push more amount of water . Now the principle of every action has an equal and opposite reaction applies, so now water will push frog forward as a reaction . This is the way frog swims .
Since frog is amphibian, webbed feet also help them to jump a significant height sometimes protecting them from predators .
How are frog feet different from human feet? What is the reason for this adaptation?
