Paratya curvirostris is a species of freshwater shrimp in the family Atyidae. It is endemic to New Zealand, where it is distributed from North Island to Stewart Island, and including the Chatham Islands. It is the only freshwater shrimp in New Zealand.[1]
This species has a limited range but it is common to abundant there. It lives in streams and low-salinity estuary habitat.[1] It is rarely found above 40 meters in elevation. It is associated with aquatic vegetation.[2]
The female carries up to 4000 eggs. Once they are deposited, she cleans them and provides water flow by beating her pleopods. Eggs took about 28 days to hatch in a laboratory experiment.[2]
