Yellowline Arrow Crab (Stenorhynchus seticornis) just after molting and before ingesting its former exoskeleton, Martinique, France Like most crustaceans, arrow crabs shed their exoskeleton as they age. The new skin hardens with calcium carbonate, which is acquired from sea water and by ingesting their old shell. Olympus OMD EM5 MkII, Zuiko 60mm Macro lens, Nauticam Housing, Dual Inon Z-240 Strobes.

Sponge Crab (Undetermined ID), Martinique, France Sponge crabs are real camouflage artists. They cut down chunks of sponge and wear them like a costume. The sponge continues to live and grow with the crab, sometimes covering him entirely. That’s the reason why identification can be very tricky ... as there is not enough crab showing.
