Did You Know Kangaroos Have 5 Limbs?

Kangaroos are celebrated for their hopping , but a slow - moving roo relies more on its quarter to get around than either of its pes . The result is a what life scientist call a five - limbed , i.e. “ pentapedal , ” pace . Yes , you read that right . The kangaroo is a pentaped – perhaps the only one on Earth .

Researchers pass by Max Donelan , Associate Professor of Biomedical Physiology & Kinesiology at Simon Fraser University , account for the Kangaroo ’s pentapedal position with a biomechanical analysis , the results of which appear in the latest outlet of Biology Letters . save the researcher ( stress added ):

When moving slowly , kangaroos plant their tail on the land in sequence with their front and hind legs . To determine the tail ’s theatrical role in this ‘ pentapedal ’ pace , we measure the forces the tail exerts on the ground and calculate the mechanically skillful ability it generates . We found that the tail assembly is creditworthy for as much propulsive force as the front and hind legs combine . It also generate almost exclusively positive mechanically skillful power , perform as much mass - specific mechanical work as does a human leg during walking at the same speed . kangaroo use their muscular tail to support , propel and power their pentapedal pace just like a leg .
