Via IFLScience: ‘When these types of animals occur out in the wild, they tend not to live very long. With two brains governing one body, movement isn’t always smooth and deliberate. Instead, they can disagree about how to move, making it fairly difficult to catch prey. This anomalous anatomy also makes them fairly easy prey for larger predators as well. However, two-headed snakes receiving proper captive care are able to live full, relatively normal lives and even give birth to normal offspring.’
