Frogs are amphibians from the order Anura. Unlike the salamanders, they do not have a tail. Frogs depend on water for reproduction. The larvae, tadpoles, look different from the adults. Many species occur in a humid environment. They avoid the sun and are usually active in the evening or at night. There are also animals with rougher skin and shorter hind legs, which have adapted to drier conditions. These animals were usually called toads. Recently, some toads have been found to be more closely related to frogs than to other toads. That is why toads are now counted among the frogs. Partly because of this, the number of frogs has increased to more than 6200 species. New species are still being discovered. Frogs are found all over the world, with the exception of the polar regions and some deserts. There are 11 native species in the Netherlands. The bullfrog has been introduced and can develop into a pest. Part of the species richness can be found on postage stamps.
