Zebrida adamsii lives on the urchins as do the Coleman shrimp. At dusk I found an area on the sand that was nothing but a field of fire urchins so began looking for crabs and shrimp. This Zebra Crab was easy to spot, he was huge! I signalled Kurt and Mike by firing my strobe several time in rapid succession and we all got plenty of shots. Later I found Richard, Carolyn and David who also photographed Zebra Crabs.
