Tremarctos is also the only living genus under the Tremarctinae subfamily, with the other genera, Plionarctos, Arctodus, and Arctotherium all being extinct.

They like to build nests that they use to sleep and eat in, in trees of high elevation in humid tropical rain forests.

They are considered omnivores as they eat fruit, corn, plants, insects, farm animals, and more.

[3] The word Tremarctos is derived from the Greek language and translates to "hole bear" in English.

Both species are sexually dimorphic, meaning the males are most times larger than the females in size.

Even though they are omnivores, the evidence of having short mandibles and crania indicates they feed mostly on plants and fruits and only sometimes eat meat.

Courtship occurs between male and female Tremarctos bears and this usually involves vocalizations or playful fighting.

They are also polyesterous, meaning the bears have specific breeding seasons with twins being the most common litter.

[3] While the Tremarctos bear is higher up on the food chain, it still has a couple of predators and other things that threaten them.

One of the biggest reasons for their decline is due to humans poaching and causing their habitat loss.
