Idk, I dig up and down the coast from Kittery to Calais and just this past summer there was a whale stuck out at Brookings Bay for a few days, it would surface in the same spot to breathe then sink back down, we dig this place alot and for a few days this went on. Lobstermen drop there traps up and down the center of the bay, I'm assuming the whale was tangled up in gear which is why it was stuck in the same spot for days. Of course something else could of tangled it, but if not a lobster trap another piece of fishing gear.
