Cryphiops brasiliensis
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Cryphiops brasiliensis faces severe population decline primarily due to dam construction and water diversion projects that fragment river systems and alter natural flow regimes essential for its reproductive cycle. Overfishing and collection for the aquarium trade have further reduced wild populations, while agricultural runoff and urban pollution degrade water quality in its remaining habitat. The species' restricted range along specific river basins makes it particularly vulnerable to localized environmental changes.
Habitat
This freshwater prawn inhabits clean, well-oxygenated rivers and streams with rocky or sandy substrates in southeastern Brazil. It requires specific water flow conditions and temperature ranges, typically found in mid-elevation river systems with natural flow patterns.
