Kangaroos only sweat while they are hopping. When they stop exercising, they pant, just like dogs do. A kangaroo mother may have a newborn joey and a much older baby (called a yearling) nursing at the same time. Each one will get milk that is formulated to suit him best nutritionally. Strangely, kangaroos burn less energy the faster they hop… up to 20 miles per hour. A group of kangaroos is called a mob. A male kangaroo is called a buck, a boomer, or an old man. A female kangaroo is called a doe or a flyer. For a long time, people thought the word kangaroo meant "I don't know" in an aboriginal Australian language. Probably, the word comes from gangurru, a native name for one kind of kangaroo.
