How are clams adopted for burrowing in mud and sand?

Clams are adapted for burrowing in the mud and sand by having a short siphon (tube that intakes water) that allows them to expel mud and sand from their gils. They also have adapted by using their foot to dig down into the sand. The foot pushes down through the media and then the clam can pull it self down to the tip of their foot.
