They are found in Saltwater lakes, and marshes and cannot live very long in freshwater. They lakes they live in are subtropical, and the lakes are almost alkaline, but not acid. The lakes they live in has a P.H. level of 7.0.They can live in salinity up to a 50% salt concentration, which is closely saturated. Brine Shrimp are not difficult with changes and can live in a wide selection of salinity. Brine Shrimp gills help them with the high salt content by absorbing and removing ions as when needed.
Brine Shrimp are crustaceans (phylum Arthropoda) which are invertebrate animals, this means they do not have a backbone or spinal cord. Their scientific name is Artemia salina and classified in the subphylum Crustacea. Crustaceans are aquatic and are different from other arthropods by having two pairs of appendages (antennules and antennae) in front of the mouth and paired appendages near the mouth that function as jaws. It has an elongated body divided and attached to its trunk are 10 sets of flat appendages called phyllopodia. Brine Shrimp eat photosynthetic green algae. They get food by either filtering small particles with spines on the legs as they swim and scraping algae off coral or rocks. For reproduction, a male clasps a female with his large antennae and he fertilizes her eggs, producing zygotes. Then she lays the eggs. These eggs can be diploid or tetraploid. Artemia salina eggs will hatch if conditions are right in the environment which is around 70 degrees F.
