OK, so seeing the scrawny, bulgy-eyed slender loris from Sri Lanka doesn't stir your heart the way that a Sumatran tiger does. But if you've ever watched this little guy sleep, curled up on a branch with his head between his legs, you might feel differently. You might even reach into your wallet and give what you can to help him. By making careful choices, conservationists can try to change our bias against those animals that are the antithesis of "cute." But in the end it's our own responsibility to redefine those features that we prefer. We might learn to love the aye-aye—and the hundreds of other ugly, endangered, and genetically distinct mammals out there—enough to take bold, immediate action to save them.
