They are omnivorous, meaning they eat both plants and animals, and are at the top of the food chain in their environment. They live in family groups, with the dominant male and female leading the group. The dominant male and female will mate and produce offspring, which will stay with the family group until they are mature enough to leave. The family group will also interact with other family groups, and sometimes even other species, in order to find food and resources.

How would you describe their survival instincts? Tiliqua nigrolutea, commonly known as the shingleback skink, is a reptile that has adapted to survive in its environment. It has a number of survival instincts, such as the ability to burrow into the ground to hide from predators and to detect changes in temperature and humidity in order to regulate its body temperature. It also has a keen sense of smell and sight, which it uses to detect potential threats and to find food. It is also able to detect vibrations in the ground, which it uses to detect the presence of predators. All of these instincts help the shingleback skink to survive in its environment.
