The western grey kangaroo is one of the largest kangaroos. It weighs 28–54 kg and its length is 0.84-1.1m with a 80–100 cm tail, and is about 1.3m tall. It has sexual dimorphism with the male up to twice the size of female. It has thick, coarse fur with colour ranging from pale grey to brown. It has a paler color on its throat, chest and belly. It feeds at night, mainly on grasses but also on leafy shrubs and low trees. It has a nickname "Stinker" because mature males have a curry-like odour.
