Frogs are amphibians that are known for their great jumping abilities. They are one of the very few amphibians that can jump. Frogs have large, muscular back legs that allow them to jump great distances. However, it’s not just the amount of muscle that allows them to jump so far.
Before the frog makes its leap, the muscle shortens, transferring energy into the tendons. When it is release, the tendon recoils, like a spring, propelling the frog forward. If the jumps were made simply with their leg muscles, they would not be able to jump nearly as far as they can with assistance of the energy used from their tendons. The combination of muscle and tendon makes the frog the exceptional jumper that they are.
