The Australian Platypus Conservancy, "an independent organisation dedicated to conserving the platypus and its freshwater habitats," offers this informative Web site about "one the world's most unusual animals." Visitors can learn about platypus biology and ecology in the Platypus Fact File; find out how to become involved in platypus conservation efforts; read the latest platypus-related news in Ripples, the organization's newsletter; and more. The Platypus Fact File is particularly comprehensive. This Web site should convince visitors that the platypus is a fascinating mammal for more than its ability to lay eggs.
