When you peak inside an oyster, it's remarkable what one finds. Rather than "The world is my oyster" sensu William Shakespeare, it should be changed to "The world is an oyster", as a metaphor of the vast diversity of life residing within these humble molluscs; there are magnificent microbes within.
