A large lithodid crab crawling along a rock wall

A large lithodid crab crawling along a rock wall. This crab appears to be missing its left rear leg. They will regenerate so this should be a temporary inconvenience to the crab. The two red laser dots below the crab help to determine its size as having a carapace at least four inches across and a total legspan of almost 1/2 meter.
