Paposa Snail

Chilina angusta

Unknown

Overview

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

Chilina angusta faces significant pressure from habitat degradation in its freshwater environments, particularly due to agricultural runoff and water pollution in Chilean river systems. Urban development and water extraction for irrigation have altered natural flow patterns, reducing suitable habitat availability. The species' limited distribution makes it especially vulnerable to localized environmental changes and water quality deterioration.

Threat summary

Habitat

This freshwater gastropod inhabits clean, well-oxygenated streams and rivers in central Chile, typically found attached to rocks and submerged vegetation in flowing water. The species requires stable water conditions with minimal pollution and prefers areas with rocky substrates that provide suitable attachment sites.
