Today we had a lovely Sunday afternoon, so I went sailing in my 12- 
foot catboat.  Shortly after I was under sail, just at the mouth of  
Hubley Cove into St. Margaret's Bay, I heard a snorting, breathing  
sound off the port stern.  I turned to see the blur of an aquatic  
mammal disappearing under the waves a mere ten feet away.  Then in a  
few seconds I got a better view of two cetaceans, in tandem (almost  
touching), breaking the water and breathing through their blowholes.   
They were pure black and shiny from the water, and the dorsal fins  
were very noticeably curved aft at the top.  Twice they breached  
before disappearing.  Because my boat is small and puts me very close  
to the water, I had an excellent view.

I have checked the Peterson Field Guide to the Mammals, and the best  
fit seems to be the Common Blackfish (Globicephala ventricosa).  I did  
not get to see the head, however, which would have been definitive.   
The description says that these swim in large groups, though, and I  
only saw two individuals.

Two years ago the Atlantic Harbor Porpoises showed up in the same  
area, but these were not the same.
