Not much is known about pangolin communication, but it is suspected that their main mode is via scent markings. As with all mammals, there is some visual communication, and tactile communication occurs, especially between mothers and offspring, potential mates, and potential rivals for mates. Pangolins are also known to make some vocalizations. (Medway, L, 1969; Nowak, 1999)
