The Bryozoan concealed a small limpet species underneath. A single Bryozoan began growing on the little limpet and proceeded to develop into a colony, exceeding the size of the limpet by many times and supplying unanticipated protection for the little shell, which grazes on algae and fortunately doesn't have to travel far to feed. The limpet was less than 10mm.
