The kangaroos provide meat for both humans and pet food. The neonate emerges after only 33 days. accurate. The red kangaroo's legs work much like a rubber band, with the Achilles tendon stretching as the animal comes down, then releasing its energy to propel the animal up and forward, enabling the characteristic bouncing locomotion. It typically inhabits open habitats with some trees for shade. It has the species name Macropus rufus because of it's distinctive has reddish-brown fur The Red Kangaroo Ellis, M., van Weenen, J., Copley, P., Dickman, C., Mawson, P. & Woinarski, J. Kangaroos are believed to have come from the macropodinae potoroines, the balungamayines, and the propleopines. After approximately 190 days, the baby (called a joey) is sufficiently large and developed to make its full emergence out of the pouch, after sticking its head out for a few weeks until it eventually feels safe enough to fully emerge. Joeys are thus protected in their mother's pouch. The red kangaroo (Osphranter rufus)[5] or red giant kangaroo is the largest of all kangaroos, the largest terrestrial mammal native to Australia, and the largest extant marsupial.
