Cacomistle

Bassariscus sumichrasti can grow to around 38–47 cm long, followed by a tail of roughly the same length or longer, adding an additional 39–53 cm to the entire animal's body length. The male cacomistle is often slightly longer-bodied than the female; however, both males and females weigh about the same, usually between 1 and 1.5 kg. Their bodies are usually covered in grey or light brownish fur, in stark contrast to the black-and-white, striped tail. The tail markings are most defined near the animal's posterior end, gradually fading to a solid black at the tip of the tail. To the untrained eye, Bassariscus sumichrasti may be visually confused with its close relative, Bassariscus astutus, the ringtail; however, in addition to a more northerly distribution, the ringtail, unlike the cacomistle, does not have retractable claws. The cacomistle can also be identified by its faded tail markings and ears that end in a distinct point.

The cacomistle inhabits the tropical and subtropical forests of North America (Mexico) and south into Central America, ranging through Panama. These animals are quite solitary and thus spread themselves out, with each cacomistle having a home range of at least 20 hectares (an area equivalent to 20 sports fields) and are typically seen in the middle and upper levels of the canopy. Throughout their broad range this species is found to inhabit a wide variety of different forest ecosystems. In Mexico, the cacomistle tends to avoid oak forests, secondary forest, and overgrown pastures, but in Costa Rica, the cacomistle has been shown to favor those exact habitats.

The cacomistle is usually considered a generalist species, as it can survive on a wide variety of different foods. Their diet varies from season-to-season, consisting primarily of fruits, flowers, nectar, invertebrates and also some small vertebrates, such as lizards, frogs, toads, and rodents. The specificity of these food options depends on what is available in the particular habitat in which an individual dwells. The various genera of bromeliads (Bromeliaceae family) found throughout the cacomistle's range are often an excellent source for food, especially in the southern end of the species' range, as these plants naturally collect rain water, which in turn brings insects and many small animals found high in the canopy; in addition, the bromeliad itself is often consumed by some omnivorous species.
