A notable observation during Papahānaumokuākea ROV and Mapping expedition Dive 10 was a high abundance of predatory chitons, which have not been seen elsewhere on the expedition and were a first for many of the shipboard science team. These chitons were observed frequently throughout the latter portion of the dive, often among the bases of corals (as in this image); a large portion also appeared to be free-living. Several individuals were observed in what appeared to be their hunting posture. One individual was collected for further analysis; this likely represents a new species in the genus Placiphorella.
