The Brine Shrimp's young won't hatch until there is alot of rain ( 2 times the size of a classroom even).  Even if the eggs have to blow all over the desert to find enough water.

The Shrimp's shell is like metal!  Instead of feet, it has feelers.  The only predators are mostly birds like Hawks and Pelicans.  Look at my diorama!

It mainly likes to eat plankton.
