Roaming the deserts, woodlands and forests, excluding rainforests of Australia are a group of iconic skinks- the blue tongue lizards. Due to their gentle nature in captivity blue tongue lizards, or “bluies” make excellent pets and have been popular with Australians for a very long time. Most people that grew up outside the cities are very familiar with at least one of the species.

Obviously the feature the blue tongue lizards are known for is the… blue tongues of all of the species. This marvelous piece of equipment serves more than one purpose. First of all it is used much like the tongue of a snake, the lizard flicks it in and out of the mouth to taste the air as it moves along in search of food. Secondly, when alarmed blue tongue lizards lift the head, flatten the body and flash the tongue at the threat. If that fails, the lizard follows up with a nasty bite. There is a rumor going around that these lizards may have some rudimentary venom, which seems unlikely but there may at least be some nasty bacteria present in the mouth. Old timers say that a bite from a blue tongue will re-appear once a year but this remains to be proven.
