Scientists have learned that female kangaroos are attracted to male kangaroos with buff shoulder and arm muscles. The males know this and even strike poses to show off their muscles to the females.
Humans, gibbons and large birds walk by raising one foot at a time. On the other hand, most macropods, smaller birds, lemurs and bipedal rodents move by hopping on both legs simultaneously. Tree kangaroos are able to walk or hop, most commonly alternating feet when moving arboreally and hopping on both feet simultaneously when on the ground.
Kangaroos have a unique three-stage walk where they plant their front legs and tail first, then push off their tail, followed lastly by the back legs.

The arrangement of the pouch is variable to allow the offspring to receive maximum protection. Locomotive kangaroos have a pouch opening at the front, while many others that walk or climb on all fours open in the back. Usually, only females have a pouch, but the male water opossum has a pouch that protects his genitalia while swimming or running.

Eastern grey kangaroos are polygynous which means that one male mates with multiple females. Males do a lot of intraspecific competition for mates which includes male-male fights to determine dominance between the two males. When a dominant male finds a female in estrus, he will court the female and eventually they copulate. [23]
