Clams Oysters and Scallops
Clams, oysters and scallops are bivalve mollusks native to both freshwater and saltwater habitats. Many are edible and some types of oysters produce the world’s freshwater and saltwater pearls. All questions about clams, oysters and scallops can be directed here.

What are facts about clams in tide pools?
Did you know that if they're left alone, clams can live up to about 33 or 36 years? The size of clams people eat are already 3-5 years old and the Giant Clam can live up to 100 years. And when they're young, they ride fish until they become mature enough to be independent.
How do you clean clams oysters?
Clams can be cleaned by leaving them in water for 24 to 48 hours. They will clean themselves out, but it is good to change the water a couple of times during the process. Oysters generally do not need to be cleaned and can be eaten raw out of the shell.
The clam is a mollusc, and all molluscs belong to the taxonomic domain of Eukarya.Eukarya covers all organisms in the Kingdom Animalia, as well as the Kingdoms Plantae, Fungi and Protista.
Do you have to kill oysters to get their pearls?
No, it is not necessary to kill the oysters. In freshwater pearl farming approx 32 pearls can be obtained at a time and then the mollusk is re-nucleated. Saltwater pearls can produce one pearl at a time and during a life span it can give 4-5 pearls. After that most of the time it is left in the water to live at its own.
A scallop is a marine bivalve mollusk of the family pectinidae. They are found in all the worlds oceans and are valued as a food source and to shell collectors.
they are cold blooded so if you put them in warm water they will die since they cant adapt to the temperature
What does clam movement look like?
The best answer includes two types of movement vertical which is accomplished by extending the foot into the sand or mud. The anterior end of the foot can be spread like a phalange and then the shell is pulled toward that direction. Most movement of adult clams is vertical. Clams in the surf use a type of jet propulsion by forcing water out of the shell cavity which sends the clam in the opposite dirction.
What type of symmetry is oysters?
Yes. Crabs and other crustaceans have bilateral symmetry. Bilateral symmetry means something has symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.
It depends on the clam species. Apparently, some start out as little swimming larvae, and secrete a hard shell during one of their larval stages, or when they go through metamorphosis. Other species are released from the parent's mantle cavity as fully developed little clams.
they prefer to live on hard surfaces in sheltered waters within the intertidal zone. They can survive in salinities between 10 and 32 parts per thousand, and temperatures of -1 to 35° Celcius.
There are many different species of clams, and some are much smaller than others. Scientists are still exploring, though. It will soon be found.
What is the largest shellfish called?
The Japanese Spider Crab is the largest crustacean, and also the largest arthropod.
the shell protects the clam from predators. The shell also helps make pearls when the clam has something that is irritating the clam. The irritating object has to have part of another clams mantle on it" it makes the pearl with the mother of pearl which is the shinny part on the inside of the clam.
put at least five in a tank as oysters (make sure there are some sand in the tank)are ambisexual and can slip back and forth many times as a male or female and ohhh....!! If you are lucky, a chip of sand might have slipped into an oyster and..... tadahhh!!(Boom!) Congrats!! You now have a pearl (or at least a minature one) because you might have to wait a year for a fully developed one (mabye can be your mum's next year's birthday present) or you can just keep as souvenier... :)
What does an oyster look like?
An ugly barnacle encrusted rock.this is not all true ugly is an infrence so that's not accurate. but they do look like a rock. they look like a black sedimentary rock that has been polished down.-Jacob
How often is a pearl found in a oyster?
A natural pearl begins its life inside an oyster's shell when an intruder, such as a grain of sand or bit of floating food, slips in between one of the two shells of the oyster, a type of mollusk, and the protective layer that covers the mollusk's organs, called the mantle.
In order to protect itself from irritation, the oyster will quickly begin covering the uninvited visitor with layers of nacre--the mineral substance that fashions the mollusk's shells. Layer upon layer of nacre, also known as mother-of-pearl, coat the grain of sand until the iridescent gem is formed.
Cultured pearls are made in the same way. The only difference is that instead of accidental circumstances, a "pearl farmer" embeds a grain of sand into the mollusk. But It Takes 6-8 Years to make the pearl
it can take up to 35 years for a clam to make a pearl because its lazy
It can take as little as a few months to form a seed pearl (natural). Cultured pearls vary by species and take as little as six months (short-cultured akoya) to six years (large, tissue-grafted freshwater).
Well, it depends on the type of pearl, what color and how big you would like the pearl. I'm assuming you are talking about cultured pearls, since you asked how long. Akoya pearls can take up to one to two years to culture and Black Tahitian pearls can take up to seven years to be cultured. As for natural pearls, you never know because they are natural, but the smaller ones can grow within a year.

No clams don't have feet. They move along using water currents pushed out of their shell by forcing water through their bodies to move.
Do pigs have wings?
Yes, clams are filter feeders and extract the plankton floating in the water as food.
