Why do kangaroos hop instead of walk?
Show answer & explanation
Answer: Hopping is more efficient
To move faster than predators — Wrong. Speed is a benefit, but efficiency is the main reason. Hopping uses their spring-like tendons.
Pouch babies need bouncing — Wrong. Joeys aren't why kangaroos hop. The pouch is adapted for hopping, not the other way around.
Hopping is more efficient ✓ — Correct! At high speeds, hopping uses less energy than running. Kangaroo tendons store and release energy like springs. They can cruise at 25 mph and barely get tired! At slow speeds, they use their tail as a fifth leg.
