Can someone help this person?

< We live on the water in Ocean Pines, Maryland and are on a canal connected
to the bay and Atlantic ocean.
We have a large animal of some type that lives in our canal and I cannot
either dig it out or identify it.
This thing resembles a long neck clam but the neck is about one and a
quarter inch in diameter and about six or eight inches in length.  If you
try and find it with a clam rake, it will retract and I have tried in vain
to dig it out but with no avail.   It must be better than 18 inches down.
The neck is a  whitish material and looks like a piece of plastic pipe which
it retracts into the
hole.  It is about one and half inches in diameter and when you try and
locate it it disappears for a couple of weeks before you can see it again
