Artemia -

: Major lineages include Artemia salina (Mediterranean), A. franciscana (Americas), and A. sinica (Eastern Asia).

Artemia , popularly known as or "sea monkeys," are small aquatic crustaceans that thrive in hypersaline environments like salt lakes and evaporation ponds. They are globally significant in aquaculture, serving as a primary live food source for larval fish and crustaceans due to their high nutritional value and unique ability to form dormant embryos called cysts . Key Characteristics and Biology artemia

: Adults are about 1 cm long, featuring 11 pairs of legs used for swimming, feeding (filtering algae and detritus), and respiration. : Major lineages include Artemia salina (Mediterranean), A

: They survive in salinities ranging from nearly fresh water to saturated brine (up to 300 ppt) and can withstand temperatures from 15°C to 55°C. Artemia , popularly known as or "sea monkeys,"

: They produce dormant cysts that can remain viable for decades. When environmental conditions (water, oxygen, light) become favorable, these cysts hatch into free-swimming larvae called nauplii .
