Video transcript

Yes, while rare, some snakes can have three eyes. This condition, known as a congenital defect, results in the development of an extra eye, usually on the head. A notable example is a three-eyed snake found in Australia in 2019. These anomalies occur due to embryological developmental issues and although fascinating, the extra eye typically doesn’t function.
