Stiphodon discotorquatus

Declining

Overview

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

Stiphodon discotorquatus faces severe threats from habitat degradation in its limited freshwater stream environments. Dam construction and water extraction for agriculture have fragmented its already restricted range, while sedimentation from deforestation and agricultural runoff degrades the clean, fast-flowing waters essential for this species' survival. Climate change-induced alterations to precipitation patterns further threaten the delicate hydrological balance of its mountain stream habitats.

Threat summary

Habitat

This species inhabits clean, fast-flowing freshwater streams in mountainous regions, typically found in rocky substrates with high dissolved oxygen levels. It requires pristine water quality and specific flow conditions characteristic of undisturbed tropical mountain watersheds.

Stiphodon discotorquatus faces severe threats from habitat degradation in its limited freshwater stream environments. Dam construction and water extraction for agriculture have fragmented its already restricted range, while sedimentation from deforestation and agricultural runoff degrades the clean, fast-flowing waters essential for this species' survival. Climate change-induced alterations to precipitation patterns further threaten the delicate hydrological balance of its mountain stream habitats.
Where does Stiphodon discotorquatus live?
Stiphodon discotorquatus occurs in Cook Islands, and French Polynesia. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Stiphodon discotorquatus?
The main threats to Stiphodon discotorquatus are 2.1, 5.4, 7.2, and ai-1. The full IUCN-classified threat record for this species is detailed on the species page.
