Riding home from work the other day, I nearly ran over this little guy, sunning itself on the side of the road. I don't know the species, it was less than a metre long, and no more than 25mm across. It was dark brown with darker stripes.
It didn't move while I took photos, so it was either dead or playing possum. It was definitely dead the next day though - the side of a busy road is not the best place to sunbathe.
