Characidium vestigipinne

Unknown

Overview

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

Characidium vestigipinne faces severe threats from habitat degradation in its restricted range within Brazilian river systems. Agricultural expansion and cattle ranching have led to increased sedimentation and pollution of the clear, fast-flowing streams this species requires. Dam construction and water extraction for irrigation further fragment and alter the hydrological conditions essential for its survival.

Threat summary

Habitat

This small characin inhabits clear, fast-flowing streams and small rivers with rocky or sandy substrates in the Brazilian Cerrado region. It typically occurs in well-oxygenated waters with moderate to strong currents and abundant riparian vegetation.

Why is Characidium vestigipinne classified as Critically Endangered?
Characidium vestigipinne 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. Characidium vestigipinne faces severe threats from habitat degradation in its restricted range within Brazilian river systems. Agricultural expansion and cattle ranching have led to increased sedimentation and pollution of the clear, fast-flowing streams this species requires. Dam construction and water extraction for irrigation further fragment and alter the hydrological conditions essential for its survival.
Where does Characidium vestigipinne live?
Characidium vestigipinne occurs in Brazil. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Characidium vestigipinne?
The main threats to Characidium vestigipinne are 2.1, ai-1, ai-2, and ai-3. The full IUCN-classified threat record for this species is detailed on the species page.
