Galaxaura barbata
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Galaxaura barbata faces severe threats from coastal development and marine pollution in its limited Caribbean range. Ocean acidification poses an additional risk to this calcifying red algae, potentially weakening its calcium carbonate structure. Rising sea temperatures and increased storm intensity associated with climate change further stress remaining populations in shallow reef environments.
Habitat
This marine red algae inhabits shallow coral reef environments and rocky substrates in warm tropical waters of the Caribbean. It typically grows in areas with moderate water movement and good light penetration, often forming part of the algal turf community on reef flats and lagoons.
