A few years back I posted about Andrew Zuckerman's Bird Book - a very simple documentation of a number of species of birds. The sparseness of the images was the appeal. Well, take that same concept and apply it to just about any animal and you've got Creature Book. It's a collection of all kinds of creatures - from alligators to owls to tamarin to tree frogs. I'd love to see the site grow to document one of everything but that's just absurd.
