This big fella is a Northern Resident killer whale who is designated A13, and is called Skeena. Took this photo last August up in the vicinity of Telegraph Cove. He actually came within about 10 feet of me, but as I had a telephoto and was too busy gasping for breath, I didn't get a shot off. This was my best picture of him.
Skeena, as you can see, had a run-in with a boat propellor sometime in the last couple of years; his fin used to be even taller. It doesn't appear to have affected his health.
