Pogona Barbata:

This species of bearded dragon lives along the eastern and southern coasts
of Australia. It is darker than the familiar P. vitticeps and has bigger spikes.
Possibly the largest species in the Pogona genus, some P. barbata exceed 8
inches snout-vent length. They live in a variety of habitats, including seasonally
wet forests and dry scrublands. They eat a wide variety of foods, including
insects, fruit, greens, flowers, and even smaller lizards. Their
approximate range is shown below.
