Summary
Imagen de bivalvo Family Cardiidae. This public domain image comes from a National Park Service article. There are several species of cockles that live in the sandy shoals of Cape Lookout. These bivalves bury themselves in the sand with a muscular foot and filter out organic particles from the water to eat. They can also use that foot to leap along the bottom of the ocean to escape a predator.
This image is very small, unfixably too light/dark, or may not adequately illustrate the subject of the image. If a higher-quality image is available, please consider replacing this one; otherwise, a replacement under a free license should be found or provided.
