The family nests in holes either in the soil or in arboreal termite mounds.

There are several species of gliding ant including Cephalotes atratus this may be a common trait among most arboreal ants.

There are also arboreal species of true frogs, and the family includes some of the very few amphibians that can live in brackish water.

Workers of Cataulacus muticus , an arboreal species that lives in plant hollows, respond to flooding by drinking water inside the nest, and excreting it outside.

Many New World monkeys are small and almost all are arboreal, so knowledge of them is less comprehensive than that of the more easily observed Old World monkeys.

While other mammals rely heavily on their sense of smell, the arboreal life of primates has led to a tactile, visually dominant sensory system, a reduction in the olfactory region of the brain and increasingly complex social behavior.

Small size Small size provides many advantages to arboreal species such as increasing the relative size of branches to the animal, lower center of mass, increased stability, lower mass (allowing movement on smaller branches), and the ability to move through more cluttered habitat.

The reason we personify things like cars and computers is that just as monkeys live in an arboreal world and moles live in an underground world and water striders live in a surface tension dominated flatland, we live in a social world. We swim through a sea of people a social version of Middle World.
