It is also known as the great grey kangaroo and the forester kangaroo. Although a big eastern grey male can typically weigh up to 69 kg (152 lb) and have a length of well over 2 m (6 ft 7 in), [ 4 ] the scientific name, Macropus giganteus (gigantic large-foot), is misleading: the red kangaroo of the semi-arid inland is larger, weighing up to 90 ...

[2] Sexual dimorphism can manifest itself in many different forms. In male and female primates there are obvious physical difference such as body size or canine size.
