There have been some very low tides recently - and some interesting creatures exposed. I think this tiny beast is a Gold-spotted nudibranch.
And this is the deadly stonefish. Great camouflage even though it was completely exposed it was hard to spot. I thought it must be dead at first but I then saw its gills moving. According to Grant (Guide to Fishes) it is capable of surviving at least 24 hours out of water. So glad I had my camera with me!
