An excerpt for Dru (from Bryson's book):
"For animals that need never surface, obscurity may be even more tantalizing. Consider the fabled giant squid. Though nthing on the scale of the blue whale, it is a decidedly substantial animal, with eyes the size of soccer balls and trailing tentacles that can reach lengths of sixty feet. It weighs nearly a ton and is earth's largest invertebrate. I f you dump one in a normal household swimming pool, there wouldn't be much room for anything else. Yet no scientist-no person as far as we know-has ever seen a giant squid alive. Zoologists have devoted careers to trying to capture, or just glimpse living giant squid and have always failed. They are mostly known from being washed up on beaches-particularly, for unknown reasons, the beaches of the south island of New Zealand. They must exist in large numbers because they form a central part of the sperm whales diet, and sperm whales take a lot of feeding.*
*The indigestible parts of giant squid, in particular their beaks, accumulate in sperm whales' stomach into the substance known as ambergris, which is used as a fixative in perfumes. The next time you spray on Chanel #5 (assuming you do), you may wish to reflect that you are dousing yourself in distillate of unseen sea monster."
