Artemia is a genus of aquatic crustaceans also known as brine shrimp or sea monkeys. It is the only genus in the family Artemiidae. The first historical record of the existence of Artemia dates back to the first half of the 10th century AD from Lake Urmia, Iran, with an example called by an Iranian geographer an "aquatic dog", although the first unambiguous record is the report and drawings made by Schlösser in 1757 of animals from Lymington, England. Artemia populations are found worldwide, typically in inland saltwater lakes, but occasionally in oceans. Artemia are able to avoid cohabiting with most types of predators, such as fish, by their ability to live in waters of very high salinity.

Lake Urmia is an endorheic salt lake in Iran. The lake is located between the provinces of East Azerbaijan and West Azerbaijan in Iran, and west of the southern portion of the Caspian Sea. At its greatest extent, it was the largest lake in the Middle East and the sixth-largest saltwater lake on Earth, with a surface area of approximately 5,200 km2 (2,000 sq mi), a length of 140 km (87 mi), a width of 55 km (34 mi), and a maximum depth of 16 m (52 ft).

On holidays people come to see Lake Urmia around the "Shahid Kalantari" highway that still has water. The 15 km highway was constructed by drying 85% of the boundary between the western and eastern sides of the lake. Construction of the highway has disconnected the northern and southern halves of the lake and has made natural and fundamental changes in the hydrodynamic and ecological characteristics of the lake region.
