Kangaroos conserve energy between hops using elastic mechanisms. From previous experimental studies on large animals, it was noted that during active locomotion mammals save much of the energy they would otherwise need for running by means of elastic structures in their legs.
Red kangaroos have distinctive markings in black and white beside their muzzles and along the sides of their face. Eastern grey kangaroos do not have these markings, and their eyes seem large and wide open.

[ 1 ] Most animals derive most of their energy from aerobic respiration , namely combining the carbohydrates , fats , and proteins with oxygen from air or dissolved in water . [ 2 ]
In 2009 the government put a limit of 1,611,216 for the number of red kangaroos available for commercial use.

Kangaroo meat is very lean with only about 2% fat. Their skins are used for leather.
