India is among the countries in the world that boast some of the highest levels of biodiversity. India's varied topography includes mountainous regions like the Himalayas, rainforests, deserts, mangrove forests, and tropical islands. This wide range of natural environments has made it possible for unique species to evolve over thousands, or even millions, of years in the country.There are many unique animal species in India that cannot be seen anywhere else in the world. They have stayed in forests, mountain regions, and islands that are far away from civilization. From a purple frog that spends most of its life underground to a deer that survives on floating wetlands, India’s endemic wildlife is as unusual as it is fascinating.
