This gremlin-looking creature is a primate found in Madagascar. Aye-ayes have a number of unusual traits, including a long, bony, witch-like middle finger that they use to pry insects and grubs from tree trunks.
Perhaps due to their appearance, these gentle, harmless animals are often killed because of a local superstition that aye-ayes are harbingers of death. Some believe that if an aye-aye points at you, it's a death sentence.
None of this is true, of course. These primates are peaceful, nocturnal foragers.
