|The aye aye|
Aye ayes (Daubentonia madagascariensis) are a bit...different. They're the woodpeckers of Madagascar in a way. These primates have an extended third finger which they use to tap and find larvae from wood. Those large ears help them hear grub inside the wood. Once the aye aye finds something inside the wood, it uses it teeth, specifically its incisors (tooth at the front of the jaw designed for cutting: humans have four) to tear open the wood and get to the food! It may also use its third finger or digit to extract the food.
|Note the long middle finger that helps the aye aye find food|
Here's a great video from National Geographic where you can watch this fascinating, creepy-looking primate in action: World's Weirdest-The Demon Primate. Enjoy!
