Filter Feeding Clams are known as filter feeders because of the way they eat their food. ... The cilia in the clams' gills is able to trap the tiny food particles from the water and move them down to their mouth, where they can be eaten and digested. The water is then pushed out through the other syphon.

What is the feeding method of a clam?
Clams Clean the Water by Filter Feeding
Tiny moving cilia (hair-like structures), which cover the gills, pump water through the clam, drawing it in the incurrent siphon. Suspended particles in the water are captured by the gills and moved to the mouth for ingestion.
Can a clam eat a human?
No account of a human death by giant clam has ever been substantiated, and scientists say its adductor muscles, used to close the shell, move far too slowly to take a swimmer by surprise. Even the largest specimen would simply retreat into its shell rather than attempt to sample human prey.
How do clams work?
How do clams move? Clams have the most control of their movement using their foot. ... Aside from digging into the sand, most clams then move by using water currents, which allows them to move from one region to the other. On the other hand, clams do not have a lot of control over how or where water currents carry them.
How do clams produce?
Reproduction is sexual, requiring both a male and a female. ... Male clams produce sperm and release it into the water, while females produce eggs that are retained internally. The sperm get drawn into the female bivalve through her siphons, and fertilization occurs.
Do clams poop?
Unlike the last story, the clams' faeces are well-documented. Past studies have observed the routine release of undigested and photosynthetically functional symbiotic microalgae (Ricard & Salvat, 1977; Trench et al., 1981).
Do giant clams still exist?
Tridacna gigas is one of the most endangered clam species. ... Its range covers the Indo-Pacific, but populations are diminishing quickly, and the giant clam has become extinct in many areas where it was once common.
Do clams have eyes?
Clams lack heads, but most can react to changes in light and some have eyes. All clams have two shells joined near a hinge structure with a flexible ligament, and all are filter feeders. Clams also have kidneys, a heart, a mouth, a stomach, a nervous system and an anus. Many have a siphon.
Do clams have brains?
Clams don't have a centralized brain like mammals. However, they do have a nervous system, giving them the ability to feel things and react.
How do clams burrow?
To protect themselves clams burrow down in the mud and sand using their foot. They can burrow more than 11 inches! When the tide comes in, they stick their siphons out and inhale fresh seawater to get oxygen so they can breathe.
Why do clams open their shells?
Clams close their shells with powerful adductor muscles which pull the two valves together. A springy ligament at the hinge pulls the shell open when the muscles relax. Just like us, the clam needs to use nerve cells to signal the muscle to do its thing.
How do clams get their shell?
Mantle tissue that is located under and in contact with the shell secretes proteins and mineral to form the shell. Think of laying down steel (protein) and pouring concrete (mineral) over it. Thus, seashells grow from the bottom up, or by adding material at the margins.
Why do clams produce pearls?
Mollusks make pearls as a protection against irritants that sneak into their soft tissue. They do so by exuding layer upon layer of shell material. For some animals, this material is nacre, or mother of pearl.
Does a clam come from an egg?
Clams spawn by releasing either eggs or sperm through their excurrent, or outgoing, siphon. When female clams began to spawn they were removed from the tray and placed into a separate dish of seawater to ensure an accurate count of the eggs she produces.
Do clams feel pain?
Yes. Scientists have proved beyond a doubt that fish, lobsters, crabs, and other sea dwellers feel pain. Lobsters' bodies are covered with chemoreceptors so they are very sensitive to their environments.
Do clams pee?
Like humans, clams have a bladder to store urine and kidney-like body parts called nephridia that help to filter the body's waste products. ... And instead of an anus, clams have a body part called a siphon that opens to allows water (ingested during filter feeding) and waste products to exit the clam's body.
Are clams born with shells?
No, clams aren't born with shells. They are free-swimming larvae after they hatch, and just prior to metamorphosis they secrete a hard shell.
What is inside a clam belly?
But the belly actually refers to the whole of the soft-shell clam: a firm scallop of digestive tract plus the smaller, silkier, brain-balls-heart of the thing. This circuit is connected by terrifically strong but tender muscle, and two thin siphons.
