We found a two tailed lizard in the car port yesterday. It's a Metallic Skink.- Niveoscincus metallicus.
Tail shedding is a common tactic of many lizards which increases their chance of escape from predators. It seems in this case that either the tail has not shed properly or else it has suffered some sort of injury. Either way the regeneration process has been triggered but the original tail has healed. The end result is the curious two tailed lizard shown below. It's not all that unusual as I have seen others over the years but it's always interesting none the less.
