Eastern blue-tongued lizard

In addition to flashing its blue tongue, the skink hisses and puffs up its chest to assert dominance and appear bigger when in the presence of its predators such as large snakes and birds.

The eastern blue tongue is ovoviviparous and precocial, meaning that its young are more developed and advanced at their time of birth.

The eastern blue-tongue lizard has smooth skin covered with scales that overlap and have small bone plates.

[2] These lizards' blue tongues could be an evolutionary adaptation that can assist in long-distance communication in order warn off predators and decrease aggressive activity.

[2] 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.

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 and 35 degrees Celsius when they are active.

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.

[8] When their internal temperatures reached a reproducible level when in heat, they decided to return to a more neutral environment.

[2] When these lizards are kept as pets, they often are attracted to horizontal pipes, cavities under houses, and rockeries as hiding sites.

According to a consensus published in 2017 by the San Diego Zoo Wildlife Alliance Library, the eastern blue-tongued lizard has a wide distribution and it is categorized as “least concern” in terms of endangerment.

Government regulations like the Environment Protection and Biodiversity Conservation Act in 1999 have positively influenced the preservation of the eastern blue-tongued lizard.

[10] These lizards are found in mixed woodland habitats, semi-deserts, and scrubland areas in Tasmania, Australia, and New Guinea.

As an omnivore, the blue tongued skink has a diet that consists of plants, fruits, insects, and other reptiles.

[5] Because eastern blue tongued lizards are agile, they frequently consume animals that move more slowly.

A study done on these lizards found that adults and juveniles are able to distinguish between color and shape stimuli successfully and one was not superior in learning capabilities.

For example, it was found that sexuality maturity happens at smaller body sizes in southern part of Australia than in Queensland.

[12] Blue tongued lizards can be attacked by reptile ticks which attach under their scales or inside of their ear canal.

Other predators of the eastern blue tongue include goannas, dingoes, and domestic cats and dogs.

[2] More research needs to be done on whether the skinks blue tongue is a result of an adaptation that is anti-predatory or if it serves as infraspecific communication.

Studies have been done, however, that have supported the idea that the amount of melanin that is present in the skink's skin does not heavily effect tongue coloration [15] Another interesting finding is that blue colored tongues have similar chromatic qualities to UV blue skin patches and can be reflective.

[15] The eastern blue tongue skink has an olfactory epithelium that appears to be of the pseudo stratified type and is loosely packed.
