Procaris chacei

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Procaris chacei faces severe threats from its extremely restricted range in Hawaiian anchialine pools, making it vulnerable to habitat destruction from coastal development and groundwater extraction. The species is particularly susceptible to water quality degradation from agricultural runoff and urban pollution, which can alter the delicate salinity balance of its specialized habitat. Climate change poses an additional threat through sea level rise and increased storm intensity, which could permanently alter or destroy the few remaining pools where this endemic shrimp survives.

Threat summary

Habitat

Procaris chacei is endemic to anchialine pools in Hawaii, specialized coastal water bodies that maintain underground connections to both freshwater aquifers and the ocean. These pools feature unique brackish conditions with stratified salinity levels, creating the specific environmental conditions required for this highly specialized crustacean.

Frequently asked questions

Why is Procaris chacei classified as Critically Endangered?
Procaris chacei is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Procaris chacei faces severe threats from its extremely restricted range in Hawaiian anchialine pools, making it vulnerable to habitat destruction from coastal development and groundwater extraction. The species is particularly susceptible to water quality degradation from agricultural runoff and urban pollution, which can alter the delicate salinity balance of its specialized habitat. Climate change poses an additional threat through sea level rise and increased storm intensity, which could permanently alter or destroy the few remaining pools where this endemic shrimp survives.
Where does Procaris chacei live?
Procaris chacei occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
