When oysters release larva, the larva travels with the water currents until they land on the bottom. Then they move by extending a muscle, like a foot, out of the front of their shell and drag themselves along the bottom until they find a resting spot. Once they find their resting spot they do not move again.

∙ 16y agoOysters release egg and sperm into the ocean water. When an egg and sperm unite they form a zygote which promptly grows cilia that help the zygote move about and filter feed. This stage is quite short as the young oyster quickly finds a place to settle down and begin gluing itself in place. The Oyster is one of the most sessile things that there is.

Most oysters float free on tidal movements until they attach themselves to other oysters or to bottom reefs. Once an oyster secretes the fluid that cements the "left hand" shell to an object, the oyster is effectively fixed in place for life.

How do clams support themselves?
Clams move around by opening and closing their shells repeatedly. They are not filter feeders like oysters or mussels. Since they swim around, water circulates through their shells, and they get their food that way. Clams' main predators are starfish. ( I think that's right...)
