Part of the Living Edens natural history series at PBS, this attractive website shares biotic wonders from Costa Rica. The site's emphasis is primarily on animals with brief descriptions for crocodiles, monkeys, poison dart frogs, butterflies, four species of marine turtles, and more. For teachers, the website offers two lesson plans--on frogs and volcanic soil--designed for grades five through seven with lesson objectives, national science standards, material needed, assessment recommendations, and more. For anyone planning a visit to Costa Rica, the site contains an overview of several national parks. The website also contains a collection of annotated web resource links.
