| Cacomistles are similar to their close relatives, Ringtails, but are smaller and have longer ears and hind legs. Their tails are distinctly longer, and more of the tail is black. They are completely nocturnal, and can be heard making loud, wailing calls at night, perhaps to stake out territories as they forage for fruit and hunt small vertebrates. Male and female home ranges can overlap, but males exclude other males, and females exclude other females, from their territories. They are more arboreal than Ringtails, denning high in trees, sleeping in holes or on shady branches. They can be locally common in various kinds of forests, but their distribution is patchy.
Head and Body: 430-740 mm; Tail: 390-530 mm
