A novel with intelligent sperm whales which I PARTIALLY read in a supermarket book display back about the 1980s I guess. Obviously it counts as at least partially fantasy and science fiction.
I would like to mention the books as an example of somewhat incomplete research in a historical list I am writing. In the story whale culture remembered two whales who had fought against 19th century whalers, who were obviously supposed to be the whale who sank the *Essex in 1820 and Mocha Dick.
I would like to point out that if the author had done more research instead of limiting himself to the most famous hero whales he could have mentioned several others who wold likely be remembered by intelligent sperm whales.
The whale novel plot description which comes the closest seems to be Sounding by Hank Searls, 1982, but I haven't found detailed enough descriptions to be certain.
