Brine shrimp are the half-inch-long crustacean colloquially known as sea monkeys and are one of the few organisms that can survive in Utah's Great Salt Lake (GSL), Brandi Klingerman writes for Phys.org.   
     
More than a low-maintenance pet, brine shrimp produce eggs, or cysts, that can be dormant, shipped around the world, hatched, and used as nutritious fish food in aquaculture. That seafood is then likely to end up at your local grocery store or favourite restaurant. Each year the GSL supplies up to 45 percent of the world's brine shrimp cyst needs and to collect them, harvesters skim the floating cysts off the top of the lake while sinking cysts remain.
      
New research completed at the University of Notre Dame's Environmental Research Centre (UNDERC) – West indicates that as sinking brine shrimp cysts remain while many floating cysts are removed, the brine shrimp population is shifting to contain more sinking cysts.
