The changeable oligodon is a small non-venomous snake with a striped pattern on its back. It lives in South Asia and uses special teeth to feed on eggs of other reptiles.
The changeable oligodon differs from other snakes with its special teeth for opening eggs. It helps maintain balance in nature by reducing the population of some reptiles.
