Cobscook Bay in Maine has got the cooties - literally. SFGate is reporting that a recent survey of the waters there confirmed that the bay is now home to the slimy blobs known as Didemnum, a genus of sea squirts whose taxonomy has been rather tough to determine. One biologist is surmising that the colonial tunicates arrived in the nearby Damariscotta River via the imported Japanese oysters that were once being farmed there. Cobscook Bay is the northernmost sighting of this creature so far on the east coast of North America.
