world’s largest quahog, a giant hard-shell clam (Mercenaria mercenaria) that has earned a place in world record history due to its extraordinary size and weight. Quahogs are a staple of New England’s coastal culture, prized both for their culinary value and their role in marine ecosystems—but this specimen stood far beyond the ordinary.

The record-setting quahog was discovered along the Massachusetts coastline and measured significantly larger and heavier than typical clams of its species. Weighing several kilograms and featuring an unusually thick, wide shell, the quahog astonished marine experts and shellfish harvesters alike. Its age was estimated to span several decades, reflecting the species’ slow growth and remarkable longevity.

Marine biologists note that quahogs can live for over 100 years under the right conditions, making them valuable indicators of ocean health. The discovery of the world’s largest specimen provided scientists with rare insight into growth patterns, environmental stability, and the resilience of shellfish in cold Atlantic waters.

Local historians and seafood experts describe the giant quahog as part of New England folklore. “Quahogs are woven into our coastal identity,” said a regional marine specialist. “This record-breaking find represents both the richness of our waters and the traditions of shellfishing communities.”
