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.
Why are cockles bad?
Due to the low caloric intake, cockles are an ally of diet food. Unfortunately, like other shellfish, they are a source of considerable doses of cholesterol: a molecule essential for the body, but when taken in excessive amounts can impair cardiovascular health.
What are the predators of cockles?
Predators find it difficult to pierce the shell of adult cockles. Sea birds drop cockles from high up, smashing their shells, to eat the body, but fish (such as flounder) can't break the shells. Younger cockles are more vulnerable to predation because their shells aren't as hard as adult cockles.
How do cockles and mussels feed and what do they feed on?
Feeding. Both marine and freshwater mussels are filter feeders; they feed on plankton and other microscopic sea creatures which are free-floating in seawater. A mussel draws water in through its incurrent siphon.
How long do cockles live for?
How long does a cockle live? The lifespan of a cockle clam ranges from five years to 10 years.
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.
Are cockle shells edible?
A cockle is an edible, marine bivalve mollusc. ... True cockles live in sandy, sheltered beaches throughout the world. The distinctive rounded shells are bilaterally symmetrical, and are heart-shaped when viewed from the end.
Why do cockles bleed?
So it is sometimes also called the Blood cockle. This is due to the presence of haemoglobin, the same substance that colours our own blood red too. Haemoglobin assists in transporting oxygen within the body and may help the clams live in the oxygen-poor habitats.
Why are cockles called cockles?
The origin of this phrase could be "cochleae cordis", a Latin medical term referring to the ventricles of the heart, or cockles, a type of mollusc, which can be heart-shaped (zoological genus was once Cardium).
Are pipis and cockles the same?
As nouns the difference between pipi and cockle
is that pipi is urine while cockle is any of various edible european bivalve mollusks, of the family cardiidae, having heart-shaped shells or cockle can be any of several field weeds, such as the corncockle, , and lolium temulentum .
How big do cockles get?
Distributed worldwide, they range from about one centimetre (0.4 inch) in diameter to about 15 centimetres (about 6 inches)—the size of the smooth giant cockle (Laevicardium elatum) of California. The two valves of the shell are equal in size and shape, and range in colour from brown to red or yellow.
What is the purpose of cockles?
In their role as filter feeders, cockles also provide an important link in the food web between the primary producers, such as phytoplankton, and smaller carnivores, such as birds, crabs and rock lobsters.
Do cockles taste like clams?
COCKLES -- small, sweet briny bivalves -- pack more flavor than littleneck clams. But because they've become widely available only in recent months, they are relatively unfamiliar to many cooks and can be slightly daunting.
How can you tell how old a cockle shell is?
How do scientists determine the age of a clam? Just like counting the rings of a tree, you can count the rings on a clam. Darker rings are created in fall and winter, possibly because of colder water and changes in food abundance. Growth of shells considerably slows as the clam gets older.
What is the difference between cockles and mussels?
is that mussel is a small edible bivalve shellfish of the families unionidae (fresh water mussels) and mytilidae (salt water mussels) while cockle is any of various edible european bivalve mollusks, of the family cardiidae, having heart-shaped shells or cockle can be any of several field weeds, such as the corncockle, ...
