What are brine shrimp?

Detailed explanation-1: -Q. In the 1980’s, the water level dropped and the salt concentration doubled in Mono Lake. How did this affect the brine shrimp population? The brine shrimp population increased.
Detailed explanation-2: -In order to survive, brine shrimp have adapted to control the amount of salt that enters their body by two means. One is a neck gland that acts as a pump to take out a lot of salt in the body in high salinity waters or to take out a little salt in the body when in low salinity waters.
Detailed explanation-3: -Brine Shrimp can tolerate a vast range of salinity from 25 to 250 grams per liter, with an optimal range of 60 to 100 grams per liter. They prefer a range from 30 to 35 grams per liter, the problem is Brine Shrimp encounter more predators at that level of salinity.
