Maxillipius commensalis Lowry, is reported as an ectocommensal on arborescent gorgonaceans from coral reefs at Madang, Papua New Guinea. The family is reviewed and the male of this species is described. In-situ behavior studies show the amphipods to crowd close together in large numbers on one side of a gorgonian stalk. The terminal articles of the sixth pereopods are greatly elongated and whip-like and are waved at the sides in a circular motion, possibly facilitating spacing or feeding. When disturbed, the amphipods react en masse as a coherent group rather than as individuals.
