The helmet crab's exoskeleton is shrouded in fine hairs, which, many suspect, help it navigate and locate objects in a dark environment. Creatures like the hermit crab are what drew photographer David Hall to the sea. "When I was ten years old, I dreamed of a career in entomology, and to this day arthropods—insects and other animals with jointed legs and an outer skeleton—hold a special fascination for me," he writes. "After mollusks, there are more species of arthropods in the ocean than any other kind of animal."
