specimens were empty shells taken from inside old discarded bottles. Signs of predation by octopi were evident on most of the specimens, so it is likely that the bottles served as a lair and that the prey was collected from within the foraging range of the octopuses. It is suspected that the shells were occupied by hermit crabs, which were then preyed upon by the octopuses (Boatman & Harasewych, 2014).
