  Did you know that the contents of your stomach can digest you? The poison in the snakes is produced by special cells and the poison is locked up in special glads that have protective lining just the same way that your stomach has a protective lining so that you don’t digest yourself! When hunting or in danger, the snake releases the poison via specialised methods (eg fans) that inject the poison directly on the prey. This way the rest of the snake’s body does not come in contact with the poison.
