- Located in California.
- Live in deep vernal pools and ponds; non marine and non riverine waters. (within annual grasslands)

Problems:
The shrimp are threatened by:
- urban sprawl: the shrimp's habitat is very desireable building grounds for housing developments.
- agribusiness
- off-road vehicles
- livestock grazing
- wetland draining
- pollution
- invasion of non-native plants
- fire

Solutions:
- The government denied disignating a critical habitat for the shrimp at first.
- However, in 2005, the US Fish and Wildlife Services designated a critical habitat for the shrimp.
