Where do cockle shells live?
Most species live just below the low-tide line; some have been obtained from depths of more than 500 metres (1,500 feet), and a few live in the intertidal zone. All are found in sandy or muddy areas shallowly buried to a depth of not more than three centimetres (about one inch).
What do cockles feed on?
