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.

Please see Category:Image cleanup templates for templates used to mark images that only need a clean-up. For more help, see Commons:Media for cleanup#Low quality images.
