Beach Walk

[Clam drawing] Clams have shells made of two halves which are hinged together with 1 or 2 large muscles to keep the shell pulled shut. Clams have a foot for burrowing. Clams have 2 siphons - 1 brings in water, which flows over the gills extracting oxygen & trapping food particles, which are sent to the mouth. The water is then expelled through the other siphon.
