South India is a peninsula in the shape of a vast inverted triangle, bounded on the west by the Arabian Sea, on the east by the Bay of Bengal and on the north by the Vindhya and Satpura ranges. The narrow strip of verdant land between the Western Ghats and the Arabian Sea is the Konkan region. The Andaman and Nicobar islands lie far off the eastern coast of India, near the Tenasserim coast of Burma. The southernmost tip of mainland India is at Kanyakumari (Cape Comorin) on the Indian Ocean.
There is a wide diversity of plants and animals in South India, resulting from its varied climates and geography. Deciduous forests are found along the Western Ghats while tropical dry forests and scrub lands Deccan thorn scrub forests are common in the interior Deccan plateau. The southern Western Ghats have high altitude rain forests called the South Western Ghats montane rain forests. The Malabar Coast moist forests are found on the coastal plains.
