Three maybe four inches large, tiny guy, not on par with a tiny hermit crab but he was small. And he was shy. All that hard shell protection and they are very afraid to be out in the light. Which begs the question, where do they catch all the crabs in the market? When they are big enough to eat, are they more stupid too? We were on a night dive. These crabs are sometimes seen at night if you manage to surprise them. The problem is that when you see one you are surprised about as much. So I got a shot. Not much else, and then he was gone. I only posted a single image because that’s all I got. Bye. No second chance.
