生物學特性     字彙 (例如 epibenthic)

Inhabits steep outer reef walls, often present in groups of up to 20 individuals which are loosely aggregated and perched vertically on the substrate at the back of small overhangs and crevices. Non-type specimens collected were also nearly always found on steep outer reef walls (Ref. 102609).
