Nu, so Melville wasn’t a Biologist either. LOL.
But, one doesn’t have to be a Biologist to be an author...or a Supreme Court Justice either I guess. :-)
Too true, but Ishmael’s monologue gives insight to the thinking process that as recently as a few hundred years ago would classify a whale as a fish.
That’s why pretty much everyone would consider a whale a fish in Old Testament times.
