The giant clam gets some of its food by filtering the seawater with its siphon.
The giant clam gets some of its food by filtering the seawater with its siphon. The siphon is fringed with tentacles that attach to food particles in the water. This creature, however, gets most of its nourishment from zooxanthellae, algae that lives within the clam’s tissue. This mutualistc relationship between two separate organisms was designed by the Creator to help the clam obtain the great amount of nourishment it needs to survive.
