Senyumia granitica

Unknown

Overview

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

Senyumia granitica faces severe threats from limestone quarrying and mining activities that directly destroy its specialized granite cave habitats. The species' extremely restricted range makes it particularly vulnerable to habitat modification, with even small-scale disturbances potentially eliminating entire populations. Urban development and infrastructure projects in the surrounding areas further fragment the remaining suitable habitat.

Threat summary

Habitat

This species is endemic to granite cave systems and underground cavities in limestone karst formations. It inhabits the dark zones of caves where humidity levels remain consistently high and temperatures are stable year-round.

Frequently asked questions

Why is Senyumia granitica classified as Critically Endangered?
Senyumia granitica 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. Senyumia granitica faces severe threats from limestone quarrying and mining activities that directly destroy its specialized granite cave habitats. The species' extremely restricted range makes it particularly vulnerable to habitat modification, with even small-scale disturbances potentially eliminating entire populations. Urban development and infrastructure projects in the surrounding areas further fragment the remaining suitable habitat.
Where does Senyumia granitica live?
Senyumia granitica occurs in Malaysia. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Senyumia granitica?
The main threats to Senyumia granitica 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.
