This decapod is commonly known as California freshwater shrimp, and is the only extant decapod shrimp in California that occurs in non-saline waters (its congener Syncaris pasadenae from the basin of the Los Angeles River is extinct). [6] [7] S. pacifica is one of only four members of the family Atyidae in North America. [7]

Triops longicaudatus (commonly called American tadpole shrimp or longtail tadpole shrimp) is a freshwater crustacean of the order Notostraca, resembling a miniature horseshoe crab. It is characterized by an elongated, segmented body, a flattened shield-like brownish carapace covering two thirds of the thorax, and two long filaments on the abdomen.
Freshwater shrimp are any shrimp which live in fresh water. This includes: Any Caridea (shrimp) which live in fresh water, especially the family Atyidae; Species in the genus Macrobrachium; Macrobrachium ohione, the Ohio River shrimp; Macrobrachium carcinus, sometimes called the American giant freshwater prawn
By the 1980s, the annual inflow of fresh water into the bay was reduced to about 40% of historic levels. [7] Following prolonged droughts, the shrimp population declines, and following wet years, it rebounds. In 1996, after two wet years, the shrimp population was 20 times larger than it was in 1980, following the severe drought of the late ...
Syncaris is a genus of shrimp, containing only two species: the endangered California freshwater shrimp, Syncaris pacifica, and the extinct Pasadena freshwater shrimp, Syncaris pasadenae. [ 1 ] [ 2 ] This genus is one of only two genera of freshwater Atyid shrimp found in North America, with the other being the genus Palaemonias , which ...
California fairy shrimp tend to live in large, fairly clear vernal pools and lakes. However, they can survive in clear to turbid water with pH of 6.1–8.5, and they have been found in very small pools. They are tolerant of water temperatures from 5–29 °C (41–84 °F), making them the most heat tolerant fairy shrimp in California.
Palaemon paludosus lives in fresh water or slightly brackish water, usually in lakes. [3] It is nocturnal, remaining hidden among the vegetation by day, and emerging at night to feed on plankton. [6] It is an important prey item for a number of birds and fishes, [7] such as black bass, [8] and may be considered a keystone species. [9]
