The potto is nocturnal and arboreal, sleeping in foliage by day. It is generally slow, moving by climbing rather than by leaping, but it can make quick grasps with its hands and mouth. Females defend an area large enough to support themselves and their young. Older and larger males establish individual home ranges from which other males are excluded, but which overlap the home ranges of one or more females. The potto leaves urine trails about 3 feet long on branches, apparently as a means of communication.
