Animal Facts
Red kangaroos often live in the desert areas of Australia and as such can withstand temperatures up to 44°C.
Red kangaroos are the largest living species of marsupial.
Female kangaroos may be pregnant, have a new-born joey in their pouch and have an older joey still milk-feeding from them all at the same time.
Red kangaroos go through four sets of molars in their lifetime.
Female kangaroos can store a fertilised egg and delay getting pregnant until their previous joey has left the pouch; this is called ‘embryonic diapause’.
