The "true" tree frogs belong to the family Hylidae but members of other frog families have independently adopted an arboreal habit, a case of convergent evolution.

They feed on insects and fruit, and their broad bills and weak legs reflect their diet and arboreal habits.

It is unclear if the Cuscomys truly are extremely rare, as they may be easily overlooked due to their remote distributions and arboreal habits.

They argued that an arboreal habit was most likely for all of the Avisauridae.

Due to its arboreal habits,this lizard can be quite difficult to observe in its natural habitat but is actually usually quite common across its range.

Because of its nocturnal and arboreal habits, the Philippine tarsier is most likely to fall prey to owls, or to small carnivores which it can encounter in its canopy homes.

The rate for carnivorans (0.65) was slightly lower yet, while primates, perhaps constrained by their arboreal habits, had the lowest rate (0.39) among the mammalian groups studied.

Their broad bills and weak legs reflect their diet and arboreal habits.

Although some of its morphological traits, such as the very large pads, are suggestive of arboreal (tree-dwelling) habits, most specimens were collected in pitfall traps on the ground.

The spider monkey has an arboreal habit and rarely ventures onto the forest floor.
