"The word 'nautilus' comes from the Greek for boat. When the first shells arrived in Renaissance Europe, collectors were stunned: They saw the perfect spirals as reflecting the larger order of the universe. Later on, Victorian homes displayed them as curios. In his famous 1858 poem 'The Chambered Nautilus,' Oliver Wendell Holmes admired 'the silent toil' that produced the 'lustrous coil.' And in 'Twenty Thousand Leagues Under the Sea,' Jules Verne created a watertight submarine of many compartments and christened it the Nautilus."
—While we marvel today at how stupid we are for ridding the world of its most amazing species because we like to wear their bodies as jewelry (or, as the case may be, to grind them up into powders and pills we take to achieve erections), it presents a good opportunity to also think about the fusion jazz keyboardist Bob James. His spirally, universe-reflecting "Nautilus" is one of the most frequently sampled tracks in rap music history. (James credits CTI records founder Creed Taylor for coming up with the title, because of the tones that sound like a submarine.) Here are fifteen excellent songs made from "Nautilus" that don't threaten anything with extinction.
And here's a video of a chambered nautilus swimming in the ocean. It is super-cool.
