Tanzania is highly biodiverse and contains a wide variety of animal habitats. On Tanzania's Serengeti plain, white-bearded wildebeest (''Connochaetes taurinus mearnsi''), other bovids and zebra participate in a large-scale annual migration. Tanzania is home to about 130 amphibian and over 275 reptile species, many of them strictly endemic and included in the International Union for Conservation of Nature's Red Lists of countries. Tanzania has the largest lion population in the world.
