📖 Overview

This species is apparently rare and relatively deepwater with specimens collected between 35-70 m. It appears to be a solitary species, with only 1 or 2 specimens collected from each site. Three of the collection sites were steep reef walls exposed to significant current, with individual specimens observed perched upright in small crevices in the coralline-algae-encrusted wall. Two other collection sites were in the mixed coral rubble and sand at the base of steep reef slopes in 35 m depth, with individuals resting on top of medium-sized rubble pieces and disappearing under the rubble when closely approached .
