Dog cockles are filter feeders, filtering plankton and organic particles from water. This filtration process supports ecosystem health by preventing the build-up of excess nutrients.

Unlike other bivalves, the dog cockle does not form colonies but burrows individually. It uses its strong foot to dig into the substrate, typically at depths ranging from 10 to 100 metres, depending on environmental conditions. This burrowing behaviour allows it to avoid environmental stresses such as tidal changes.

Although not commercially important, dog cockles are sometimes used locally for consumption or as bait. Their hard, durable shells can also be repurposed for crafts or decorative items. While not as threatened as other bivalves, pollution, particularly from industrial runoff, can affect their habitats and overall health.

Conservation efforts are crucial to maintaining the health of marine ecosystems, including the protection of habitats where dog cockles live. Ensuring clean, healthy waters will support their survival, alongside many other important marine species.
