Neoarius taylori

Declining

Overview

Potamosilurus taylori is a species of fish in the family Ariidae. It is found in Indonesia and Papua New Guinea.

Neoarius taylori faces severe population decline primarily due to habitat degradation from agricultural runoff and urban development in its limited river systems. Dam construction and water extraction have altered natural flow regimes critical for spawning, while introduced species compete for resources and prey on juveniles. The species' restricted range makes it particularly vulnerable to localized environmental changes.

Threat summary

Habitat

This freshwater catfish inhabits slow-flowing rivers and tributaries in northeastern Australia, preferring deeper pools with muddy or sandy substrates. It requires clean, well-oxygenated water with natural flow patterns for successful reproduction and juvenile development.

Frequently asked questions

Why is Neoarius taylori classified as Critically Endangered?
Neoarius taylori 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. Neoarius taylori faces severe population decline primarily due to habitat degradation from agricultural runoff and urban development in its limited river systems. Dam construction and water extraction have altered natural flow regimes critical for spawning, while introduced species compete for resources and prey on juveniles. The species' restricted range makes it particularly vulnerable to localized environmental changes.
Where does Neoarius taylori live?
Neoarius taylori occurs in Papua New Guinea. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Neoarius taylori?
The main threats to Neoarius taylori are 3.2, 5.4, 8.1, and ai-1. The full IUCN-classified threat record for this species is detailed on the species page.
