📖 Overview

This species was found on steep, volcanic-sand slopes; under small pieces of coral rubble and volcanic rock that were often covered with Halimeda algae. Strong thermoclines were frequently encountered between 40-50 m on these slopes, thus consequently this species is likely exposed to temperatures ranging from about 24-29º C .
