Vernal Pool fairy shrimp (VPFS) occur in shallow seasonal and vernal pool environments within Alameda and Contra Costa counties. VPFS are listed as threatened by the USFWS. The species has evolved to adapt to seasonal pools and drought conditions by developing eggs (cysts) that can last within the dry duff of a seasonal pool for decades. The eggs hatch when pools fill, shrimp grow into adults, breed and deposit eggs, and complete their life cycle before the pool dries.
