Limpets Shells, Patellidae

We carry polished brown limpet shells and Mexican green limpet shells.  The limpet shells are from the family Patellidae and contains shore-rock dwellers.  All true limpets are vegetarians and many limpets wander about the rocks at night, but return to their original site at dawn. Limpet shells are found in cooler waters of the Atlantic and the Pacific oceans. Certain species creep over rocks, feeding on algae during high tides, but when the tide recedes they return instinctively to the same spot occupied previously, to await the return of high water. The muscular foot clings so powerfully that limpets are found in wave-swept areas where few other forms of life can survive. The keyhole limpet is named for its central opening, through which respiratory currents pass. Limpets range up to 4 in. (10 cm) in length, but most are smaller; there are several freshwater species. Limpets are classified in the phylum Mollusca, class Gastropoda, order Archeogastropoda.

All bulk bags of shell will contain some shells with chipped edges, tiny holes, blemishes and there will be some broken shells in the bags.
