This is a Pogona lizard, most commonly known as a bearded dragon. It is only a month or so old, so quite young. But what a striking looking thing he is! His name is Peanut, and he lives nearby. Eventually he will be a foot long or so, and the spikes and sag under his chin will be much more pronounced. I am sure this is not the last you will see of him on the blog here. :)
His owner and caregiver is a delightful young lady, and as this next photo will demonstrate, someone with a lot of spirit and trust. Both admirable qualities. :)
