Overview

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

Sphaeroplea annulina faces severe threats from habitat degradation due to water pollution, eutrophication, and climate-induced changes to freshwater ecosystems. The species' specialized reproductive requirements and narrow ecological niche make it particularly vulnerable to environmental disturbances that alter water chemistry and temperature regimes.

Threat summary

Habitat

Shallow freshwater pools, temporary ponds, and slow-moving streams with nutrient-rich waters, typically in temperate regions with seasonal flooding patterns. The species requires specific water chemistry conditions and temperature ranges for successful reproduction and growth.

Frequently asked questions

Why is Sphaeroplea annulina classified as Critically Endangered?
Sphaeroplea annulina is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Sphaeroplea annulina faces severe threats from habitat degradation due to water pollution, eutrophication, and climate-induced changes to freshwater ecosystems. The species' specialized reproductive requirements and narrow ecological niche make it particularly vulnerable to environmental disturbances that alter water chemistry and temperature regimes.
Where does Sphaeroplea annulina live?
Sphaeroplea annulina occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Sphaeroplea annulina?
The main threats to Sphaeroplea annulina are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
