Bells Phase Lace Monitor (Varanus varius)
The lace monitor, or tree goanna, is Australia's second-largest lizard and one of the largest lizards on Earth. The monitor is usually a dark colour, ranging from a dark blue-black to black and has a scattering of white, cream or yellow scales forming vibrant markings on its body.
A second colour form known as Bell's phase occurs in some areas of Queensland which has strong dark grey and yellow bands all along the body.
The tail is longer than the body and head together and can measure from around 1.5 metres to 2 metres.
They also have a venom gland like the related Komodo dragon.
The one above is a good 2 metres long. I also seem to be missing a chook this afternoon.
