Kangaroo leather

[8] Studies conducted by the Australian Commonwealth Scientific and Industrial Research Organisation (CSIRO) confirm that kangaroo is one of the strongest leathers of similar substance available.

Cattle hide also contains sweat glands, erector pili muscles and a distinct gradation in elastin levels, concentrated in the upper part of the skin.

Kangaroo hide on the other hand has been shown to have a highly uniform orientation of fibre bundles in parallel with the skin surface.

[14] The two most important facets of kangaroos' better ecological fit than European agricultural animals relate to their adaptation to Australia's aridity.

Kangaroos have small chest development and so require less water to breathe than placental mammals, which usually must expand a diaphragm, losing more moisture in respiration.

Kangaroos just make small pants while immobile, and in motion expand and contract their lungs effectively using their leg muscles.

Instead, its hopping leaves very small bowl-shaped depressions in the surface of even dry clay soil, which let native grass seeds carried on the wind settle into them.
