The Scrolled Jaw
Almost every picture of Moby Dick neglects this feature, I would love to see some good artistic renderings that do show it. I also wonder how the scene where Moby bites the whaleboat in half would look with this ...
"Through and through; through every plank and each rib, it thrilled for an instant, the whale obliquely lying on his back, in the manner of a biting shark slowly and feelingly taking its bows full within his mouth, so that the long, narrow, scrolled lower jaw curled high up into the open air, and one of the teeth caught in a row-lock. The bluish pearl-white of the inside of the jaw was within six inches of Ahab’s head, and reached higher than that. In this attitude the White Whale now shook the slight cedar as a mildly cruel cat her mouse. With unastonished eyes Fedallah gazed, and crossed his arms; but the tiger-yellow crew were tumbling over each other’s heads to gain the uttermost stern."
A related side note, I would love to see Ishmael depicted as he describes his older self, entirely covered in tattoos including measurements of whales and a poem he has written.
