How do kangaroos move so efficiently by hopping?
Quick Answer
Kangaroos use elastic tendons in their legs to store and release energy like springs. This makes hopping especially efficient at higher speeds compared with walking.
The Full Story
A kangaroo’s long hind legs and large Achilles tendons act like biological springs. As the animal lands, the tendons stretch and store energy, then release it on the next push-off. This reduces the effort needed for each hop, especially at steady speeds. Kangaroos also use their large tail for balance and as a support when moving slowly. Their unique hopping style is one reason they are so well adapted to covering long distances in open Australian habitats.
