Gillellus chathamensis

Unknown

Overview

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

Gillellus chathamensis faces significant pressure from habitat degradation in its limited coastal range around the Galápagos Islands. Introduced species, particularly feral goats and invasive plants, have altered the terrestrial ecosystems that influence nearshore marine environments where this species occurs. Coastal development and increased tourism activities in the Galápagos have led to sedimentation and pollution in shallow marine habitats. Climate change poses additional risks through ocean warming and acidification, which may affect the species' prey base and reproductive success.

Threat summary

Habitat

This endemic fish species inhabits shallow coastal waters and rocky reefs around the Galápagos Islands, typically found in areas with mixed sandy and rocky substrates. It occurs in nearshore marine environments where terrestrial runoff meets oceanic waters, creating unique ecological conditions.
