The Common Cockle lives on muddy and sandy shores, between the high tide and low tide mark, and is commonly found in estuaries. It is a medium-sized clam-like shell, rounded and domed with radiating ridges. It feeds by filtering plankton and other organic matter from the water.

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).
Where do you find cockles?
There are more than 205 living species of cockles, with many more fossil forms. The common cockle, (Cerastoderma edule), is widely distributed around the coastlines of Northern Europe, with a range extending west to Ireland, the Barents Sea in the north, Norway in the east, and as far south as Senegal.
What do cockles feed on?
Like other bivalves, cockles don't have heads. To eat, they pump water across their gills and catch phytoplankton (tiny plants). They then move the phytoplankton into their mouths. This process is called filter feeding.
What do cockles need to survive?
Cockles need food and oxygen to survive. They have adaptations to carry out gas exchange and feed. They have gills that carry out gas exchange underwater when the tide is in. The gills do two jobs – take in oxygen and filter out fine food particles.
How do cockles breathe?
They draw water into one [they inhale through the inhalant siphon] and pump it out of the other [they exhale through the exhalant siphon]. Cockles are buried in the seafloor with their siphons opening just above the mud or sand.
What are cockles of the heart?
The phrase “cockles of your heart” refers to the cockle-like ventricles of the heart. ... Corculum cardissa (heart cockles) have tiny windows in their shells that let in light for their internal algae to photosynthesize.
Where can I find cockle beds?
HABITAT – COMMON COCKLE
Also common on sheltered flash beaches along the middle and lower shore. Lays buried under a couple of inches of sand, but can often be seen poking through the surface as the tide recedes. Common cockles form large beds on some estuary flats, but prove more widespread along true beaches.
What are cockles called in Australia?
Cockles are also known as Venus shells and can be found from NSW to southern Western Australia, including Tasmania.
What are cockle shells?
Definition of cockleshell
1a : the shell or one of the shell valves of a cockle. b : a shell (such as a scallop shell) suggesting a cockleshell. 2 : a light flimsy boat.
Do cockles have brains?
It's highly unlikely, due to them not having any brain or central nervous system. All they have is a small nerve network and two ganglia near their esophagus. The whole nervous system is basically two nerve centers, one that controls the muscles and the other one that controls the "foot" and other sensory organs.
What are cockle shells made of?
The analysis of crystal structure using XRD illustrates that raw cockle shell is made up of aragonite, CaCO3. It is one type of crystal form of calcium carbonate other than calcite and vaterite.
How do cockles live?
What is a cockle's habitat? The typical cockle habitat consists of soft mud and fine sand in subtidal areas. They prefer larger grain size sediments and are usually found in sand flats and eelgrass beds. They have been found in water depths of up to 65 ft (20 m) in some places, but they prefer shallower environments.
How do cockle shells move?
GIANT POLISHED COCKLE SHELL
The Giant Cockle as well as other cockle shells move thru the water by using their long powerful foot. The foot allows them to several inches as they move across muddy or sand bottom sea floors.
What are cockles predators?
Birds are a major predator of cockles (up to about 23 mm shell length). However, they appear to have little impact on cockle abundance. Other predators include crabs and whelks. Cockles are also killed after being smothered by sediments shifted during storms or strong tides.
