What are the behavioural adaptions for a snake?

Behavioural Adaptation: A Red Belly Black Snakes is able to find small positions to get away from predators, as they have adapted to hide in small cracks, holes and logs as this enables the snake to get away from predators.

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
