I went for a walk this morning and was lost in my thoughts as I approached home, not realising a water dragon (big lizard) was sunning itself on the path in front of me - until it burst into motion as I was only a couple of steps away! Startled me a little. It dashed away and paused on the road to look back, but not for long enough for me to get out my camera/phone before it scuttled under a parked car. There were lots of sightings along there near the creek, and in my own yard, last summer, but haven't seen any for months. I guess they only like warm weather. It was probably as long as my arm to my fingertips, but I've never heard of them to be aggressive. I like them.
