: 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.

: 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 .

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

: Adults are about 1 cm long, featuring 11 pairs of legs used for swimming, feeding (filtering algae and detritus), and respiration.
