Animal
Hard clam
Mercenaria mercenaria
Also known as: quahog, northern quahog, littleneck, cherrystone
The native bivalve of Atlantic and Gulf-coast estuaries — and historically a foundational shellfish of New York Harbor. Buried in sand or muddy sand near tidal flats and shallow bays. Indigenous wampum (white and purple shell beads used as currency and ceremonial material) was made from quahog shell. Hard clams persist in waters around Staten Island, including Raritan Bay; the species is one of the targets of NY Harbor shellfish-restoration efforts.
Scientific
Mercenaria mercenaria is a 2–4 inch heavy-shelled bivalve native to Atlantic and Gulf coasts of North America. Buried in sand or muddy-sand substrate in shallow bays and estuaries. Filter-feeders. Long-lived (40+ years possible).
Multiple commercial size classes: littleneck (smallest, ~1–2 inches across), cherrystone (~2.5 inches), chowder (largest). Major commercial fishery on the U.S. Atlantic coast.
Indigenous Northeastern peoples used quahog shells to make wampum — purple and white shell beads strung on cordage, used as currency, ceremonial material, and historical record. Wampum was central to indigenous-European trade economies in the 17th century.
On Staten Island
Hard clams persist in Raritan Bay and waters around the borough. Indigenous and colonial-era hard-clam fisheries were significant; modern populations are reduced from historical levels. NY State and partner organizations are working on harbor-shellfish restoration alongside the [[billion-oyster-project|Billion Oyster Project]]‘s work.
Recreational shellfishing in [[new-york-city|NY Harbor]] is heavily restricted due to water-quality concerns; consumption advisories apply.
