The tentacles of a queen scallop provide an early warning by detecting chemicals associated with approaching predators.

Edit Hook


“The eyes are not the [queen scallop’s] only source of warning — the tentacles around the mantle edge are extremely sensitive to certain chemicals, and can probably detect the approach of a starfish long before its shadow falls, certainly in time for the scallop to close its valves or leap away.” (Foy and Oxford Scientific Films 1982:118)
