Artemia is a genus of aquatic crustaceans known as brine shrimp. Artemia, the only genus in the family Artemiidae, has changed little externally since the Triassic period. The historical record of the existence of Artemia dates back to 982 from Urmia Lake, Iran, although the first unambiguous record are the report and drawings made by Schlösser in 1756 of animals from Lymington, England. Artemia populations are found worldwide in inland saltwater lakes, but not in oceans. Artemia are able to avoid cohabitating with most types of predators, such as fish, by their ability to live in waters of very high salinity up to 250‰.
The ability of the Artemia to produce dormant eggs, known as cysts, has led to extensive use of Artemia in aquaculture. The cysts may be stored for long periods and hatched on demand to provide a convenient form of live feed for larval fish and crustaceans. Nauplii of the brine shrimp Artemia constitute the most widely used food item, and over 2000 tonnes of dry Artemia cysts are marketed worldwide annually. In addition, the resilience of Artemia makes them ideal animals for running biological toxicity assays and is now one of the standard organisms for testing the toxicity of chemicals. A breed of Artemia is sold as a novelty gift under the marketing name Sea-Monkeys.

Famous quotes containing the words brine and/or shrimp:
“I dreamed my genesis in sweat of death, fallen
Twice in the feeding sea, grown
Stale of Adam’s brine until, vision
Of new man strength, I seek the sun.”
—Dylan Thomas (1914–1953)
“To tell you the truth, I’m relieved that the Van Ripers are not coming. He’s telling the same jokes he told twenty years ago and she dyes her hair. I think it’s a shrimp pink now.”
—Adele Comandini, and Edward Sutherland. Michael O’Brien (Charles Winninger)
