The Zoological Society of San Diego brings to the web the San Diego Zoo, the San Diego Wild Animal Park, and the Center for Reproduction of Endangered Species. Each unit of the zoo has a main page, from which the user can meet the animals and find out about the humans who watch over them. The photographs of new arrivals at the zoo should be a big draw, and there is informative text underlying the visuals. The "Guest Book" is a game in which users attempt to match animals with their "signatures": the tracks they leave. Use the table of contents to find your way to the animals you're most interested in.
