Fairy shrimp cannot survive any significant amount of predation. They live primarily in vernal pools. Fairy shrimp are not the same as glass shrimp aka ghost shrimp, PK shrimp. Fairy shrimp are not 'true' shrimp. F shrimp are classified in a completely different taxomomic group or Order and are basically adult brine shrimp. They are considered a primitive (very early development) relative to most other Crustacans. Unique critters and they swim upside down, thus their high vulnerability to predation. About 27 species in North America.
