Not a good idea to venture into the sea without sandals if these are about!
I'm not sure of the species. However this one is quite big, and as you can see I'm running into depth of focus problems even at f#32. I even had to employ a "trick" here to getting it looking as it does in this shot. Can you spot what the "trick" was?
