Boselaphus Tragocamelus, commonly known as the nilgai, is a large mammal native to the Indian subcontinent. There are various synonyms for this species, including blue bull, nylghau, oryx, and nilgau antelope. The blue bull is a herbivorous animal that can reach a height of up to 5 feet at its shoulder and weigh up to 600 pounds. It is typically found in open forests, grasslands, and scrublands, and is known for its distinctive short, curved horns. The nilgai is an important game animal and has been hunted for both sport and meat, but its numbers are now protected under laws in India.
