Scobinancistrus pariolispos

Declining

Overview

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

Scobinancistrus pariolispos faces severe pressure from dam construction and hydroelectric development along the Tapajós River system, which fragments its habitat and alters critical water flow patterns. Deforestation in the surrounding Amazon basin increases sedimentation and agricultural runoff, degrading water quality in the rocky substrates this species requires for feeding and reproduction. The ornamental fish trade also poses a significant threat, as this attractive pleco species is highly sought after by aquarium enthusiasts, leading to targeted collection from wild populations.

Threat summary

Habitat

This species inhabits fast-flowing rocky areas of the Tapajós River system in the Brazilian Amazon, where it feeds on algae and biofilm growing on submerged rocks and boulders. It requires well-oxygenated waters with strong currents and complex rocky substrates that provide both feeding opportunities and shelter from predators.
