Quokkas
Based solely on how cute they are, quokkas should be the most popular animals in the world. But unfortunately, they’re still fairly little-known. So what makes the quokka so incredible?
It’s simple: thanks to their bone structure, quokkas always appear to be smiling. You can find these marsupials on the small islands off the coast of Western Australia.
Some people have even dubbed them the “happiest animal in the world,” according to National Geographic.
