Another type of chameleon that lives on Madagascar, Brookesia betschi. These little creatures have a strange mating ritual -- the male lets himself be carried around by the female before the act. With its almost 300 frog varieties and 400 different reptiles, the fauna of Madagascar is considered unique. And new species are found on the island nation with astounding regularity. At the same time, however, many of them are extremely endangered, with the International Union for the Conservation of Nature estimating that some 40 percent of the reptile species in Madagascar are threatened, acutely threatened or in danger of extinction.
