Since giant clams cannot move themselves, they adopt broadcast spawning. They release sperm and eggs into the water. A transmitter substance called Spawning Induced Substance (SIS) helps synchronize the release of sperm and eggs to ensure fertilization. The substance is released through a syphonal outlet. Other clams can detect SIS immediately. Incoming water passes chemoreceptors situated close to the inccurent syphon, which transmit the information directly to the cerebral ganglia, a simple form of brain.
In other words... Nope
they dont move in the water...because if they sit in the water for a long time theyll die..thats why you always see them not in the water
No they can't. They have no fins or anything that helps them swim. The just sit on the ocean floor and make pearls.
Clams do not actually swim and are mostly moved by water currents. Some types of clams do move by taking in water and then spitting it out.
Clams do not swim, but most are able to burrow in a soft sand or mud bottom to hide from predators.
No, the are mollusks
yes
Calms live about three feet deep in water, under the sand. They need water to live, and if something moves them they will still be in the water.
Clams are predated mostly by sea stars and some molluscs.
Raccoons will eat anything they can get their paws on, including clams.
no
Frogs do not have tails when they grow up, but they can swim in water. When in water, they can swim using their webbed feet and hind legs.
Clams use energy by opening and closing their shells to create a water current to push them so they can move.
only fresh water clams can not salt water
to burrow themselves
clams live mostly in cold water.
No, they will move to find and open clams by pumping water through its legs - they are not sessile.
Yes. Just like baby clams, they need to burrow in the sand.
Clams don't do a lot. They sit at the bottom of a lake and move very slowly across the sandy floor. They have an appendage called a foot they use to slowly move and they have have another appendage that sticks out of the shell to suck in water which they use to filter out alga and plankton which is what they eat.
Clams release eggs or sperm into the water. They meet in the water. The eggs hatch in the water. That is how clams reproduce.
Clams eat plankton, not algae. Algae grows in still water. Clams need the water to be moving so they can get nutrients.
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...)
Fresh water clams live in fresh water and salt water clams live in salt water.There are both freshwater and saltwater clams. Mussels fall into this category as well. See the related links for both.
Yes clams can suffocate when they cannot get oxygen from the water.
