Aye-ayes are among the strangest primates on Earth, with their oversized ears, spider-like hands, and — as new research shows — a previously undetected sixth finger.
Madagascar’s history contains some truly enormous animals, from giant lemurs to giant tortoises. The island was also home to 3m-tall flightless birds, which sadly disappeared hundreds of years ago. But how we humans classified those birds was, well, a mess.
The aye-aye is about as ridiculous looking as a primate can get: Beady yellow eyes, bat-like ears, and hands like horrible spiders. But perhaps its most interesting feature is its teeth.
