A single specimen was collected from 4 m depth on the reef crest, from a small burrow in the top of a large Porites coral bommie, and this reef crest has many large Porites and other massive corals, transitioning into branching and foliose corals occupying the reef slope at a 45° angle to a maximum depth of 40-50 m (Ref. 137777).
