Human Interaction
For millennia, molluscs have been a source of food for humans, as well as important luxury goods, notably pearls, mother of pearl, Tyrian purple dye, sea silk, and chemical compounds. Their shells have also been used as a form of currency in some preindustrial societies. Their outlandish forms have helped conjure up tales of mythological sea monsters, such as the kraken. A number of species of molluscs can bite or sting humans, and some have become agricultural pests.

Famous quotes containing the words human and/or interaction:
“There is a time of life somewhere between the sullen fugues of adolescence and the retrenchments of middle age when human nature becomes so absolutely absorbing one wants to be in the city constantly, even at the height of summer.”
—Edward Hoagland (b. 1932)
“Our rural village life was a purifying, uplifting influence that fortified us against the later impacts of urbanization; Church and State, because they were separated and friendly, had spiritual and ethical standards that were mutually enriching; freedom and discipline, individualism and collectivity, nature and nurture in their interaction promised an ever stronger democracy. I have no illusions that those simpler, happier days can be resurrected.”
—Agnes E. Meyer (1887–1970)
