Diplodon pfeifferi

Unknown

Overview

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

Diplodon pfeifferi faces severe pressure from water pollution and sedimentation in South American river systems, particularly from agricultural runoff and urban development. Dam construction and water extraction for irrigation have altered natural flow regimes essential for this freshwater mussel's reproductive cycle. Mining activities in watershed areas contribute heavy metals and sediments that degrade water quality and smother benthic habitats where the species feeds and reproduces.

Threat summary

Habitat

This freshwater mussel inhabits sandy and muddy substrates of rivers and streams in South America, particularly in the Paraná River basin. It requires well-oxygenated waters with moderate flow rates and depends on specific fish hosts for larval development during its complex reproductive cycle.
