ou may know koala bears for being the cute little animals that eat leaves all day and carry their babies in a pouch. In fact, koalas' scientific name means "ash-colored pouch bear."
But did you know that koalas are not actually bears at all? They are more closely related to kangaroos than they are to bears. Koalas spend most of their lives in trees. In fact, they don't even come down very often to drink water because the leaves they eat hold most of the water their bodies need.
Koalas are excellent tree climbers because they have sharp claws and an extra "thumb" that helps them hold on to trees. Did you know koalas even have fingerprints? They are the only animal besides humans and primates, like monkeys and chimpanzees, that do. (Kayleen Hartman, staff writer)
你或許知道無尾熊是終日食用樹葉、把寶寶放在育兒袋裡帶著走的可愛小動物。事實上，無尾熊學名的意思是「灰色的袋熊」。
不過，你知道無尾熊其實不是熊嗎？相較於熊類，牠們在血源上還比較接近袋鼠。無尾熊幾乎一輩子都待在樹上。事實上，由於無尾熊食用的樹葉含有牠們身體所需的大部分水分，牠們甚至很少下來喝水。
無尾熊爬樹的技藝高超，因為牠們除了有鋒利的爪子，還多了一根「姆指」，可以幫牠們牢牢抓緊樹木。你知道無尾熊甚至還有指紋嗎？無尾熊可是除了人類、猴子和黑猩猩等靈長類之外，唯一擁有指紋的動物。 （翻譯：賴美君）
