The photo was taken at the entrance to Katlian Bay. The whale is coming up to scoop up a mouthful of herring. The kayaker is a local Sitka Dentist. The whale's mouth is fully open with the bottom half under the boat by Mark Tennant.
Let me make a short, opening, blanket comment. There are no good guns. There are no bad guns. Any gun in the hands of a bad man is a bad thing. Any gun in the hands of a decent person is no threat to anybody - except bad people.
