Peba-II is an on-line animal encyclopedia which produces descriptions and comparisons of animals as world wide web pages. The Peba system contains information about hundreds of animals, but it has more information about Australian Monotremes (the Echidna and Platypus) and Marsupials (such as the Kangaroo, Koala and Wombat). There is also a lot of information on the cat family (Lion, Cheetah, Tiger, Leopard, Snow Leopard etc), and lots of other mammals like the Alligator, Porcupines (American and African), Elephants (African and Indian), Rabbit, Baboon, Gorilla, Plains Zebra, Goat, Sheep, and so on.

The system produces descriptions and comparisons of animals by using underlying representation of information, similar to a database. The web pages you are given do not exist on the server, but are dynamically created as and when you ask for information. Because the descriptions are created by a system, the system can adapt the descriptions to your particular knowledge or experience. The system thus produces web pages that describe or compare animals, with embedded hypertext links.
