The Rhinoceros unicornis, commonly known as the Indian rhinoceros or one-horned rhinoceros, is a large herbivorous mammal native to the Indian subcontinent. It is characterized by its single horn, thick gray skin, and large body, which can weigh up to 2,200 kilograms. This species primarily inhabits grasslands and forests, particularly in India and Nepal. Indian rhinos are known for their unique skin folds, which resemble armor plating. They are generally solitary animals, except for mothers with calves. The species is classified as vulnerable due to habitat loss and poaching for their horns, which are highly valued in some cultures. Conservation efforts are ongoing to protect their populations.
