When snakes are born with two heads, they fight each other for food and Sometimes they'll even try to eat each other.

When snakes are born with two heads, they fight each other for food and Sometimes they'll even try to eat each other.

Two-headed snakes do not have a long life expectancy, particularly in the wild. Each head has a brain and, usually, some control over the shared body, and the two cannot communicate with each other. Movement is therefore difficult, as each head may try to travel in a different direction.

Some two-headed snakes share a stomach, while others have a stomach for each head. In a two-headed snake with separate stomachs, one of the heads may die if it routinely loses fights over food. Even if there is only one stomach, two-headed snakes may not be able to capture prey if the heads are competing for food. Despite this, two-headed snakes have lived up to 20 years in captivity. Researchers think that the inbreeding of snakes for zoos and pets may lead to an increased incidence of two-headed snakes. In 2000, a two-headed snake named We earned a bid of $150,000 on eBay.
