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:
“Life is not a matter of place, things or comfort; rather, it concerns the basic human rights of family, country, justice and human dignity.”
—Imelda Marcos (b. 1929)
“UG [universal grammar] may be regarded as a characterization of the genetically determined language faculty. One may think of this faculty as a ‘language acquisition device,’ an innate component of the human mind that yields a particular language through interaction with present experience, a device that converts experience into a system of knowledge attained: knowledge of one or another language.”
—Noam Chomsky (b. 1928)
