Knowra Kangaroo locomotion Kangaroo locomotion Kangaroo locomotion is movement by kangaroos, distinguished on land by coordinated hopping on powerful hind limbs and a tail that helps support and balance the body.
Saltatory locomotion : Locomotion in which an animal travels through repeated leaps separated by airborne phases. Kangaroo hopping is a prominent form of this leaping gait.
Red kangaroo : The largest living marsupial, native to much of mainland Australia. Its long hind limbs and hopping are among the best-studied examples of kangaroo locomotion.
Locomotion energetics : The study of energy use during animal movement across speeds, gaits, and environments. Kangaroo hopping raises questions about how energy costs change with speed and body size.
Bipedalism : A form of locomotion in which an animal moves primarily on two legs. Kangaroos are bipedal, but their usual traveling gait is hopping rather than human-like walking.
Pentapedal locomotion : A slow kangaroo gait using both forelimbs, both hind limbs, and the tail as five points of contact. It contrasts with hopping and lets kangaroos move slowly while grazing.
Macropodidae : The marsupial family that includes kangaroos, wallabies, and several related groups. Kangaroo locomotion is one expression of the broader macropod body plan.
Elastic energy storage : Temporary storage of mechanical energy in stretched elastic tissues or materials. Tendon recoil returns energy between hops and helps reduce the cost of travel.
Gallop : A fast four-beat gait used by many quadrupedal mammals, with periods when all feet leave the ground. A gallop is a common fast mammalian gait, unlike the kangaroo's characteristic two-legged hop.
Achilles tendon : A strong tendon connecting calf muscles to the heel bone and transmitting force during ankle movement. Elastic energy stored in kangaroo ankle tendons helps power repeated hops.
Hindlimb : A paired rear limb in a vertebrate, including its bones, joints, muscles, and tendons. The enlarged hindlimbs provide most of the force for kangaroo hopping.
