This is an interesting shot of a Jeweled Anemone Crab's defensive armament. These critters are normally found inhabiting Partridge Tun Shells. They 'arm' themselves with anemones (this one has 4) which can sting any potential adversary. I know this from a personal painful experience.(Yeah! Yeah! I know! I'm the guy that touches the paint right below the 'wet paint' sign!)
Aloha, Larry(aka previously a potential adversary)
