Zoology was one of Douglas Adams' many interests. He made a series and wrote a book Last Chance to See... about his travels around the world in search of animals on the edge of extinction.

He also contributed to BBC2's evolution weekend, discussing a lemur called the Aye-Aye.

"...When you see it is like a sort of assemblage of other sorts of animals. It has sort of ears like a fox, it has little bitey rabbit's teeth, it has eyes like a bat's, rather like Marty Feldman's eyes looking in different directions, and then it's got a tail like a giant ostrich feather. But the strangest thing is its very very thin, skeletally thin middle finger that it uses for burrowing under the bark of trees for grubs."
