Arctica [Arctica]

Description

Arctica is a genus within the family Arcticidae, commonly known as the Arctic clams. This genus is exemplified by its most famous species, Arctica islandica, also known as the ocean quahog. Arctica clams are bivalves, characterized by a roughly spherical or oval shell that is thick and strong, providing protection in their seabed habitats. These clams are known for their remarkable longevity, with some individuals living for more than 500 years. They inhabit cold, temperate waters of the North Atlantic, serving as indicators of environmental change and longevity research subjects. The genus is distinguished by its unique anatomical features, including a simple hinge structure without teeth and a robust shell composition that contributes to its longevity.
