Impossibility

When first severed, the head is dropped astern and held there by a cable till the body is stripped. That done, if it belong to a small whale it is hoisted on deck to be deliberately disposed of. But, with a full grown leviathan this is impossible; for the sperm whale’s head embraces nearly one third of his entire bulk, and completely to suspend such a burden as that, even by the immense tackles of a whaler, this were as vain a thing as to attempt weighing a Dutch barn in jewellers’ scales.

But was there no other way for the whale to land the prophet within that short distance of Nineveh? Yes. He might have carried him round by the way of the Cape of Good Hope. But not to speak of the passage through the whole length of the Mediterranean, and another passage up the Persian Gulf and Red Sea, such a supposition would involve the complete circumnavigation of all Africa in three days, not to speak of the Tigris waters, near the site of Nineveh, being too shallow for any whale to swim in.
