Physical Adaptations

One physical adaptation is that when they move quickly, they use their tail for balance. This helps them get away fast from their predators. Another physical adaption is that they use their legs and clawed feet to defend themselves from attackers. Red kangaroos can bite, which helps them when they have to battle with an enemy like a dingo. Also, they use their forelegs with heavily clawed paws for eating, grooming, and fighting. The red kangaroo's range of vision is approximately 300°, due to the position of its eyes. This helps them see their prey very easily. Another physical adaption is that the females have the unusual ability to delay birth of their baby until their previous joey has left the pouch. This is called embryonic diapause.

Behavioral Adaptations

The first behavioral adaptations is that if pursued into the water, a kangaroo may use its forepaws to hold the predator underwater to drown it. Another behavioral adaption is that kangaroos feed mainly by night and rest during the heat of the day. This means that they will not get dehydrated during the day and this helps them with avoiding predators during the day. Also the kangaroo digs deep into the ground to get water. This helps them survive so again they don't get dehydrated. When a kangaroo hears an intruder or a loud noise, the kangaroo straightens up and leaps off its powerful back legs. This helps to either attack or run for it! Another behavioral adaption is that they carry around their joeys to keep them safe.
