Cacomistle
Bassariscus sumichrasti · also called cacomistles, cacomixtle
High in the forest canopy after dark, a cacomistle leaps confidently between branches, its long, bushy tail streaming behind for balance, a close relative of the ringtail that has taken life off the ground far more seriously than its rock-dwelling cousin.
Overview
The cacomistle, Bassariscus sumichrasti, is a highly arboreal, nocturnal mammal native to forest habitat across a range spanning southern Mexico and Central America. Its close relationship to the ringtail, proportionally longer balancing tail, and near-total commitment to life in the forest canopy make it one of the more specialised and rarely observed members of the raccoon family found in the Americas.
The ringtail’s more committed tree-dwelling cousin
While its close relative the ringtail still spends considerable time scrambling among rocks and cliffs, the cacomistle has instead taken to the trees almost entirely, rarely touching the forest floor at all.
Status
Least Concern, widespread and stable across suitable forest habitat throughout southern Mexico and Central America.
Cacomistle: common questions
How is the cacomistle different from the ringtail?
This species is a close relative of the ringtail, but has a proportionally longer, more heavily furred tail and spends nearly all of its life in the trees, whereas the ringtail spends considerable time on the ground and among rocky terrain rather than remaining almost entirely arboreal.
Why does the cacomistle have such a long tail?
This species uses its long, heavily furred tail primarily for balance while leaping between branches high in the forest canopy, an adaptation well suited to its far more consistently arboreal lifestyle compared with its ground-dwelling ringtail relative.
When is the cacomistle active?
This species is almost entirely nocturnal, foraging for fruit, insects, small mammals, and birds after dark and remaining hidden within tree cavities or dense foliage during daylight hours, making it rarely seen despite being fairly common within its range.
Does the cacomistle help forests grow?
Yes, by consuming fruit and later depositing the seeds elsewhere through its droppings as it moves through the canopy, this species contributes meaningfully to seed dispersal within the forest habitat it occupies across southern Mexico and Central America.
