Delhi Zoo opened its gates in 1959, changing its name to the National Zoological Park of Delhi in 1982. Located near India Gate in the heart of New Delhi, the zoo is spread out across more than 170 acres and is home to almost 130 species of animals and birds from around the world.The National Zoological Park aims to house animals in a similar way to which they would live in their natural environments. It houses a number of endangered species, which it helps to breed in captivity with the aim of eventually releasing them to thrive again in the wild.The grounds can be explored either on foot or by using one of the zoo’s electric buggies. Just some of the larger mammals visitors can expect to encounter include chimpanzees, lions, hippopotamus, African buffalo, Indian elephants, giraffes, spider monkeys, and zebras. There are also a number of migratory bird species of note, along with water birds, crocodiles, hyenas, macaques, and jaguars. An underground reptile house is located at the center of the zoo.
