blue tongues could be an evolutionary adaptation that can assist in long distance communication in order warn off predators and decrease aggressive activity. Habitat Tiliqua scincoides scincoides are found in the coastal plain and lower Blue Mountains in Sydney, Australia and in the majority of New South Wales and Cobar. Eastern blue tongues frequent in the open country and take shelter among large objects on the ground like logs or rocks or among leaf litter. Blue tongued lizards are incapable of producing their own body heat, as are all lizards. Because of this, they spend their mornings in the sun before looking for food in order to maintain their body temperature which is between 30-35 degrees Celsius when they are active. In the winter, however, when the weather is cold, lizards bury themselves in their shelter sites and are not active. These lizards only leave their shelters on days where the sun is out, so that they can bask in the sun. They infrequently leave the comfort of their hollow logs and ground debris. Temperature regulation Tiliqua scincoides scincoides are behaviorally regulated by their internal temperature which is a direct result of the peripheral temperature and the temperature of their brains. In a study done in 1969, the behavior of this species was observed between warm and cold environments. The results of this study suggested that when the lizards were inactive, they chose to move to a place that was cooler, therefore causing their internal temperatures to decrease. When their internal temperatures reached a reproducible level when in heat, they decided to return to a more neutral environment. It has also been found that juvenile lizards utilize higher environmental temperatures and thermo-regulate more often than adult lizards. Conservation status Eastern blue tongued lizards may eat poisonous snails and slugs that have been tainted by snail baits. If these lizards are living in a garden, they may be exposed to snail baits and insecticides that can cause them harm. Because blue tongued lizards are able to squirm through small holes in fences and under fences, they may be faced with garden pests or chemicals used by neighbors. When these lizards are kept as pets, they often are attracted to horizontal pipes, cavities under houses, and rockeries as hiding sites. The Tiliqua scincoides scincoides shows signs of having a stable population, whereas its sister species, the Tiliqua scincoides intermedia appears to have
