Caridina tumida

Unknown

Overview

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

Caridina tumida faces severe threats from habitat degradation in its limited freshwater range. The species is particularly vulnerable to water pollution from agricultural runoff and urban development, which alters the delicate water chemistry required for its survival. Dam construction and water extraction for human use have further fragmented and reduced available habitat, while invasive species introduction poses additional competitive pressure on this already restricted population.

Threat summary

Habitat

This freshwater shrimp inhabits clean, well-oxygenated streams and rivers with specific water chemistry requirements. It typically occurs in areas with rocky substrates and moderate water flow, often in headwater streams that are particularly sensitive to environmental changes.
