Diplodon fontaineanus

Unknown

Overview

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

Diplodon fontaineanus faces severe population declines primarily due to water pollution from agricultural runoff and urban development in its freshwater habitats. Dam construction and river channelization have fragmented populations and altered natural flow regimes essential for reproduction. Sedimentation from deforestation and intensive agriculture has degraded water quality, while invasive species compete for resources and alter ecosystem dynamics.

Threat summary

Habitat

This freshwater mussel inhabits rivers and streams with sandy or muddy substrates in southeastern South America. It requires clean, well-oxygenated waters with stable flow regimes and is typically found in areas with moderate current and adequate host fish populations for larval development.

Why is Diplodon fontaineanus classified as Endangered?
Diplodon fontaineanus is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Diplodon fontaineanus faces severe population declines primarily due to water pollution from agricultural runoff and urban development in its freshwater habitats. Dam construction and river channelization have fragmented populations and altered natural flow regimes essential for reproduction. Sedimentation from deforestation and intensive agriculture has degraded water quality, while invasive species compete for resources and alter ecosystem dynamics.
Where does Diplodon fontaineanus live?
Diplodon fontaineanus occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
