Occasionally found in large numbers on beaches, and in this case underwater, these  shells are actually egg cases, made by female Paper Nautilus, Argonauta hians. The tiny male Argonauts have no shell and die soon after mating, while females live in these delicate shells, which also serve as egg cases until  their brood hatches, after which the females die and the shells are abandoned.  Similan Islands, Thailand, Andaman Sea, Indian Ocean
