Which of the following is a mammalian adaptation that helps animals survive in water?

Step-by-step solution

1. Step 1: Consider what helps animals move efficiently in water – features that reduce drag and aid swimming.
2. Step 2: Webbed feet increase surface area, acting like paddle wheels, which is useful for aquatic animals.
3. Step 3: Long ears, sharp claws, and thick fur are adaptations for other environments (cold, hunting, arboreal life).
4. Step 4: Therefore, webbed feet are the correct answer.
