Barnacle and the Shellfish Free Diet

Barnacles belong to the infraclass Cirripedia within the subclass Thecostraca, making them close relatives of crabs and lobsters. They are sessile organisms, meaning they attach themselves permanently to submerged surfaces such as rocks, ship hulls, and even whales. Barnacles have a calcareous shell and are commonly found in marine environments worldwide. They feed by filtering plankton and other small particles from the water using their feather-like appendages called cirri.
