Euphyllia paraglabrescens

Local name: ハナサンゴモドキ

Unknown

Overview

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

Euphyllia paraglabrescens faces severe pressure from coral bleaching events driven by rising sea temperatures, which have intensified in frequency and severity across its Indo-Pacific range. The species is particularly vulnerable to ocean acidification, which impairs its ability to build and maintain its calcium carbonate skeleton. Collection for the marine aquarium trade poses an additional threat, as this attractive coral is highly sought after by collectors.

Threat summary

Habitat

This hard coral species inhabits shallow tropical reef environments in the Indo-Pacific, typically found on reef slopes and lagoons at depths of 5-30 meters. It requires clear, warm waters with stable salinity and strong water circulation to support its symbiotic zooxanthellae.
