"This is the ship of pearl, which poets feign, sails the unshadowed main / and its dim dreaming life was wont to dwell /as the frail tenant of its growing shell." Oliver Wendell Holmes described this remarkable creature in his 1858 poem “The Chambered Nautilus.”
Holmes was a doctor, essayist, Harvard professor and Supreme Court justice. However, the brilliant Holmes got the chambered nautilus wrong. It is not "a frail tenant."
