The Denver Zoo welcomed a new member to its family on August 8: an aye-aye lemur! She is super cute, and reminds us why we should take care of the planet. Aye-ayes, along with other lemurs, are endangered. Aye-ayes are also super rare — so much so that experts don’t even know how many there are in the wild. This cutie was named Tonks, and she might just be worth a flight out to Denver.
