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.
