What is the body structures of clam?

Clams are marine mollusks with two valves or shells. Like all mollusks, a clam has a mantle which surrounds its soft body. It also has a muscular foot which enables the clam to burrow itself in mud or sand. The soft tissue above the foot is called the visceral mass and contains the clam’s body organs.

How do clams live?

Soft shell clams live in the intertidal zone, the wet area exposed between high and low tide. Clams are under the water during high tide and are uncovered on the tide flats during low tide. To protect themselves clams burrow down in the mud and sand using their foot. They can burrow more than 11 inches!

What is the importance of clams?

Clams play an important role in the cycling of nutrients, including nitrogen (N). Clams do not absorb nitrogen directly from their environment, rather they feed on naturally-occurring phytoplankton, which use dissolved inorganic nitrogen, available in the water, to grow.

Can clams See?

Our simple answer is “They can see you!”. Giant clams possess several hundred small pinhole eyes (or also known as ‘hyaline organs’) on the exposed mantle (Kawaguti & Mabuchi 1969; Land 2003). These ‘eyes’ are light-sensitive, which allows them to detect changes in light levels, i.e. dark versus light.

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.

Can clams swim?

Scallops and file clams can swim by opening and closing their valves rapidly; water is ejected on either side of the hinge area and they move with the flapping valves in front.

Do clams swim?

Are clams good for the environment?

Not only are they delicious and nutritious, but they’re also a more environmentally friendly choice than fish and crustaceans. Clams, mussels, and oysters are bivalves and members of the invertebrate mollusk family.

Why are clams animals?

What are facts about clams?

A clam that is 2 to 3 inches is more and likely three to five years old.

What is the classification of a clam?

Clam, in general, any member of the invertebrate class Bivalvia—mollusks with a bivalved shell (i.e., one with two separate sections). More than 15,000 living species of bivalves are known, of which about 500 live in fresh water; the others occur in all seas.

How many shells does a clam have?

Clams have two shells of equal size connected by two adductor muscles and have a powerful burrowing foot. Clams in the culinary sense do not live attached to a substrate (whereas oysters and mussels do) and do not live near the bottom (whereas scallops do).

What are the adaptations of the giant clam?

Prey Adaptations: The Giant Clam closes its shell when it detects a predator by noticing the change of light. The shell of the Giant Clam has 4 to 6 folds that make it appear wavelike, These can fool predators into believing that it has teeth. The Giant Clam slowly closes its halves together, to protect its vulnerable parts from predators.
