Malva sylvestris is a species of the mallow genus Malva in the family of Malvaceae and is considered to be the type species for the genus.

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

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.

For example, Indonesia has reported about 700,000 fishing boats, 25 percent of which are dugout canoes, and half of which are without motors.
