The barnacles that comprise this cluster are crustaceans that, while free-swimming as juveniles, cement their heads to hard surfaces as adults and form a hard shell. They are filter feeders, feeding on microscopic plankton. The barnacles are healthy, high-quality marine animals shipped directly from our collector. Collections are made weekly to ensure that you receive the finest quality materials possible.
