          The eastern brown snake is an extremely well adapted organism. Its body structure allows it to squeeze through many small places. The snakes rely on mostly the olfactory glands, and especially a specialized grove on the roof of the snake’s mouth called the Jacobson’s organ. This groove is designed for the snake to analyze chemicals taken in by its tongue from the surroundings. The Jacobson’s organ is used for catching prey, because the snake’s eyes are not very good at seeing objects and are more for seeing movement.

          This snake has a very small head to body ratio compared to most snakes, its head and neck region are very similar in size. It has a very complex respiratory system as well. It is composed of one lung being much larger than the other and the heart having three chambers for the assurance that as much blood as possible is being enriched with oxygen before being pumped out of the heart.

        The Eastern Brown Snake has very well adapted fangs which are set in the front of its mouth with venom that seeps out when biting something which is common in only vipers and cobra family. However these organisms are not directly related so this would be a case of convergent evolution. Members of the viper family include rattlesnakes and pit vipers along with many other species of venomous snakes.
