Adaptations for Aquatic and Aerial Movement · NCERT Biology

In amphibians like frogs, 'webbed feet' are an adaptation for:

  1. Gripping slippery surfaces when walking on land
  2. Clinging to branches when climbing trees
  3. Increasing surface area for efficient swimming
  4. Loosening soil when burrowing underground
Show answer and explanation

Correct answer: Increasing surface area for efficient swimming

Webbing between the toes creates a paddle-like effect, increasing the surface area of the foot. This allows the animal to push more water backward, facilitating efficient propulsion in an aquatic environment.
