I believe they are brought in by birds. The birds may have the clam larve on their feet and they fly to different ponds where they come off.
Some examples of animals that live in lakes and ponds are fish, frogs, freshwater clams among many other animals.
Clams are not exclusively found in freshwater; they can also inhabit saltwater environments. However, certain species, known as freshwater clams, thrive in rivers, lakes, and ponds due to their specific adaptations for lower salinity levels. Factors like water temperature, oxygen content, and availability of food sources influence their distribution. Thus, while some clams are found in freshwater, many others live in marine ecosystems as well.
That depends on the species, as there are freshwater clams.
No, consumers.
No.
you should eat freshwater clams/oysters
False. Ponds do not form where freshwater and saltwater meet. They are usually man-made.
Freshwater clams are filter feeders, so tiny foods like daphnia and rotifers and cyclops work well.
You tell me.
In freshwater ponds.
yes
Like all clams, they have evolved into a specialized environment over time. Clams began as marine mollusks, but some of them developed the ability to survive in freshwater places where rivers empty into the sea. Those that were able to move further up the river had less predation and survived again. This goes on until freshwater clams are fully a part of the ecosystem and fit in with freshwater predators and freshwater mollusk diseases and have life-cycles and reproduction that matches the advantages of the environment.
