Blue tongue skinks (BTS) are a popular lizard pet kept in homes around the world. These lizards are native to Australia, new Guinea and Tasmania, where they live in a mixture of scrubland, woodland and semi desert areas. The blue tongue skink is omnivorous, which means it eats animals and plants, which comprises mostly of insects, plants and some other reptiles.

What makes these reptiles stand out is their long blue tongue, which is a defensive mechanism, protecting the lizard against predators. These are very docile reptiles which rarely will show any aggression. They are shy and enjoy hiding in their shelters. When they feel threatened, they open their mouth to display their blue tongue, puffing out their body while they hiss. The body puffing increases their size, making them look larger than they are, while the tongue shows them as dangerous.

The majority of blue tongue skink species you purchase are bred in captivity due to Australia prohibiting the export of their wildlife, which includes lizard. The four common skinks you will find on the market is the Northern blue tongue skin, which is from tropical Australia, the Eastern blue tongued skink from temperate Australia, the New Guinean blue tongued skink from New Guinea and the Blotched blue tongued skink which comes from south eastern Australia, which also offers a temperate climate.

What Are Morphs

Morphs (sometimes called phases) are very popular in the reptile world. This is when a lizard is different from the parents due to altered DNA and genes. The majority of morphs are bred, but morphs do occur naturally as well. Altering the DNA and genes results in offspring that are a mutation, changing skin colors, patterns and behaviors.

Bearded dragon morphs and leopard gecko morphs are very popular in the reptile community. When selecting a lizard, the majority of owners will make their selection based on colors and patterns.
