Rusty was born to run.
Whether it is to attract a female, escape a predator, or find food.
Kangaroos are the kings of sprinting.
Among mammals, the kangaroo possesses one of the most efficient aerobic physiological systems.
Even more than that of a racehorse and certainly more than ours.
His heart, much larger than one might think,
twice the size of a deer's.
Half of Rusty's weight consists of muscle, a muscular mass
80% concentrated in the basin and thighs, making it one of the most muscular animals in the world.
Its physiology is so efficient that it uses less energy to breathe while jumping than when at rest.
