Video: Shocking moment snake eats chameleon

This video shows the moment a British photographer experienced a "David Attenborough moment" when she managed to capture a chameleon being circled and eaten by a deadly snake.

Paula Webster was in Madagascar's Andasibe National Park, which is home to 155 sq km of protected rainforest, when she spotted the snake eyeing up its prey.

Warning: Watching the video isn't for the fainthearted.
