Egede’s animal had a serpent-like tail that appeared out of the water when the rest of the beast had disappeared. But rather than a tail, Paxton et al say, this was most likely a penis. They present photographs of well-endowed male whales, and also a drawing from Egede’s book, in which we see the sea monster’s serpent-like tail. The latter is remarkably similar to what we see in the photographs.
Herman Melville, you da man.
