Taeniophallus nebularis

Declining

Overview

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

Taeniophallus nebularis faces severe threats from rapid deforestation and agricultural expansion within its extremely limited range in the Atlantic Forest of southeastern Brazil. The species' restriction to a small area of montane forest makes it particularly vulnerable to habitat fragmentation, as even minor disturbances can eliminate critical breeding and foraging areas. Urban development pressure in the region continues to reduce available habitat, while climate change may alter the specific microclimatic conditions this endemic snake requires.

Threat summary

Habitat

This species inhabits montane Atlantic Forest remnants in southeastern Brazil, typically found in areas with dense canopy cover and leaf litter. It appears to prefer humid microhabitats within primary and secondary forest fragments at elevations between 800-1200 meters.

Frequently asked questions

Why is Taeniophallus nebularis classified as Critically Endangered?
Taeniophallus nebularis 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. Taeniophallus nebularis faces severe threats from rapid deforestation and agricultural expansion within its extremely limited range in the Atlantic Forest of southeastern Brazil. The species' restriction to a small area of montane forest makes it particularly vulnerable to habitat fragmentation, as even minor disturbances can eliminate critical breeding and foraging areas. Urban development pressure in the region continues to reduce available habitat, while climate change may alter the specific microclimatic conditions this endemic snake requires.
Where does Taeniophallus nebularis live?
Taeniophallus nebularis occurs in Venezuela. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Taeniophallus nebularis?
The main threats to Taeniophallus nebularis are 2.1, 5.3, 7.1, and ai-1. The full IUCN-classified threat record for this species is detailed on the species page.
