Transcript of Eastern Brown Snake

Where Does it Live?

The Eastern Brown Snake (officially named (Pseudonaja Textilis) is one of the most deadly snakes in the world, and is found through the eastern half of Australia (excluding Tasmania), and is also located in Papua New Guinea, although these snakes are not as prevalent there as it is in Australia.

In very cool weather, Eastern Brown Snakes become less active, slowing down their metabolism and using fat reserves. If the cold period is prolonged, for example in winter, the snake will hibernate in a sheltered spot. This is a physiological adaption, as it allows the snake to perform a function that is crucial to their survival.

Adaptions: Eastern Brown Snake
Thank you!

BEHAVIOURAL ADAPTATION:
Hiding from prey

A behavioural adaptation is something that an organism does or learns from others, and is an action that can be performed to increase chances of survival and protect the organism. A common behavioural adaptation of the Eastern Brown Snake is the ability to slightly flatten their body to hide from predators. Brown snakes often flatten the length or their bodies slightly, and then curl up and camouflage underneath or behind a rock. Snakes can also curl up into a ball and hide in holes in the ground.
STRUCTURAL ADAPTATION:
speed and agility for hunting
The lean muscular body of an Eastern Brown Snake allows the snake to travel fast in pursuit of its prey. It strikes quickly, bites its victim, and coils around it till it dies. The extreme toxicity of its venom means that the prey animal will die quickly, reducing the danger that it could injure the snake by scratching or biting. This is a structural adaptation as it is a physical component of the reptile's body that allows it to survive, and gives it an advantage when it comes to hunting prey and escaping from predators.

The Eastern Brown Snake occupies a varied range of habitats from wet to dry sclerophyll forests (Eucalypt forests) and heaths of coastal ranges, through to savannah woodlands, inner grasslands and arid scrub lands.
