Clam Digging-In on the beach

The Weather Channel has a Facebook video of a clam burrowing into the sand on a beach in Oregon last month.  It's surprisingly gross.  And the grossest part is near the end when it spits out a bunch of sandy water.   

Apparently it's a type of clam called a Pacific geoduck.  (Pronounced gooey-duck.)  It's the largest type of burrowing clam in the world.
