This started out with the Octopus very nearly getting the snake into its beak, the struggle continued for some 10-15 minutes with the snake never managing to break fully free of the arms. Eventually the snake managed to bite the octopus several times. The octopus went through a series of colour changes and released the snake. We returned about 2 hours later and couldn't find the octopus or the snake. I've never seen anything like it before and i doubt i will again!
