Ocean Quahog

The ocean quahog (Arctica islandica) is a fascinating bivalve mollusk native to the North Atlantic Ocean. Here are some intriguing facts about this remarkable clam:
Longevity:
The ocean quahog holds the title of being the longest-lived non-colonial animal known to science. Some individuals have lived for over 500 years! 🌊🐚
Appearance:
Its shell is rounder than that of the common quahog.
The periostracum (outer layer) is usually black.
On the interior of the shell, the pallial line lacks an indentation or sinus.
Unlike the common quahog, which lives intertidally, the ocean quahog resides subtidally and can only be collected by dredging.
Growth Rate and Sclerochronology:
Arctica islandica grows slowly, especially in cold areas where growth occurs primarily during summer.
One individual, affectionately named Ming the clam, was authenticated to have lived 507 years!
Its longevity has been valuable for sclerochronology, the study of growth patterns in hard tissues, aiding in modeling paleoclimates.
