The Biggest Sperm Whale's Tail

The largest sized sperm whale's tail begins at that point of the trunk where it tapers to about the girth of a man. It comprises, upon its upper surface alone, an area of at least 50 square feet. The entire member seems a dense webbed bed of welded sinews. In no living thing are the lines of beauty more exquisitely defined than in the crescentic borders of these flukes. At its utmost expansion, in the full grown whale, the tail will considerably exceed 20 feet across.
