The aye-aye lives in the forests of
Madagascar. Despite looking like a very scared rodent, the aye-aye is a kind of
lemur with a bushy tail and super-thin, elongated middle fingers that they use to dig grubs out of hollow branches. Aye-ayes also have huge lower incisors to chew through wood and bamboo—and in captivity they’ve been known to chew through
concrete cinder blocks.
