The web-feet of frogs and toads is basically for

Step 1: Analyze the question The question asks about the main function of the webbed feet (skin stretched between the toes) in frogs and toads.

Step 2: Explain the concept Frogs and toads are amphibians, so they live both on land and in water. Their hind limbs are adapted for different tasks:

• Long, strong hind legs are for leaping (jumping) on land.
• Webbed feet (a membrane of skin between the toes) increase the surface area of the foot. When the frog kicks backward in water, the foot pushes against more water, giving greater thrust, just like a swimmer wearing flippers.

Step 3: Go through the options

• A. Leaping: This is done by the powerful, elongated hind leg muscles, not by the webbing.
• B. Walking: Webbing does not help with walking. Frogs mostly hop rather than walk.
• C. Swimming: Correct. The webbing increases the surface area for pushing against water.
• D. Mating: Male frogs have nuptial pads on their forelimbs to grip females during mating, but this is not the function of the web.

Step 4: Answer The web-feet of frogs and toads is basically for swimming, which is option C.

Exam tip: Match structure to function. "Web" suggests "water," so think of ducks, frogs, and otters, all with webbed feet for swimming. Remember also that leaping comes from the long hind legs, while the webs help with swimming.
