We have been seeing finback whales almost almost everyday now. I have photographed 2 individual whales. Finbacks are identified by the shape of their dorsal fin as well as the colourations and permanent scars and marks on their back and caudal peduncle.
Here you can see the "blaze", the white markings extending from the lower right jaw over the back behind the blowhole. This blaze is used in identification.
This is another finback that we have seen. You can see we were not far from land, very close to Bliss Island. You can see the difference in the shape of the dorsal fin of this finback and the one shown above.
I will make sure to post any identifications I get. These images will be sent down to Allied Whale in Bar Harbor where they have a catalogue of North Atlantic finback whales.
