Last spring Marius posted the most awesome image of a rat lemur, also known as "Madagascar's gothest mamal," a.k.a. the aye-aye.

I recently came across audio clips of this adorable little bugger. (It would be crime to not sample these.)

Just how goth is the aye-aye? "Due to its bizarre appearance and unusual feeding habits, it is considered by many to be the strangest primate in the world. It is the world's largest nocturnal primate. Unusual physical characteristics include incisors that are continually growing (unique among primates), extremely large ears, and a middle finger which is skeletal in appearance, and is used by the animal as a primary sensory organ."
