Tarsus to Tarsier

I've had a hard time finding an ugly photo of the tarsier. Most of them are cute, what with their petiteness and binocular vision. So I had to go with freaky.

Anyone care to guess whey they're called tarsiers? It's because of their elongated tarsus bones (the bones in your foot that join to your toe bones). I'm not sure why their hand bones became the basis for their name.
