Madras Crocodile Bank

Zoo in Kovalam (Covelong)

Just 6km south of Kovalam, this incredible conservation and research trust is a fascinating peek into the reptile world. Founded by croc/snake-expert Romulus Whitaker, the bank has thousands of reptiles, including 17 of the world's 23 species of crocodilian (crocodiles and similar creatures), and does crucial work in maintaining genetic reserves of these animals, several of which are endangered. There are openings for volunteers (minimum two weeks).
