The indri is one of the largest lemurs. I always liked them because they seemed mysterious to me as a child. Back before the google, the only place I ever saw a picture of one was in the set of World Book Encyclopedias my parents had. There was only one paragraph of info, and one shadowy, indistinct picture of an indri standing up straight on two legs on the forest floor. There was a silhouette of another indri in the distance behind it. They seemed to look straight out of the picture, and looked eerily like people, so I used to imagine that they were like small sasquatches with a primitive jungle society hidden from humans.
