There are 60 species of Kangaroo. Think all kangaroos are the same? Think again. There are dozens of species of kangaroos and wallabies. There's the 2m (6ft) tall red kangaroo you'll see bounding across the outback, and then there's the musky rat kangaroo, whose tiny bodies are typically smaller than a rabbit. But one thing’s for sure - they’re all downright adorable.
