A family or group of marine mollusks (like ark shells) characterized by a bivalve shell structure, used in scientific classification.
From New Latin, based on the genus Arca (ark shell) + the taxonomic suffix -ceae, which denotes a family in biological classification systems.
Arcacea shells have been found in archaeological digs for thousands of years, and sailors used them as both food and jewelry—they're literally some of humanity's oldest tools and ornaments.
