Monkeys are mischievous and enchanting, but they can also be very destructive and dangerous to humans. Responsible tourism can help protect these endangered animals and their habitat.
Many monkeys have tails that can be used to grab branches, but some species can use their hands and feet, too. Tails that can grip and hold are called prehensile, and some monkeys use their tails to climb or carry food.
Most monkeys are arboreal, but some, like the colobus monkey and the langur, live in forest habitats that are partly terrestrial. Monkeys that feed on leaves often create heavy predation pressure on trees, and some, such as the patas monkey and the colobus monkey, sometimes kill whole groups of trees by continuously eating their foliage.
Some monkeys can use their hands and feet to get around, but others can also move on four legs—like the mandrill, from West Central Africa. They can even leap between trees!
Depending on their habits, some monkeys choose particular trees for sleep and rest. These are usually tall and isolated, so that monkeys can sleep without being exposed to malaria-carrying mosquitoes. In addition, the tree canopy can help keep the monkeys cool at night.
Some species, such as the tamarin monkey and the marmoset, are monogamous, but many monkeys live in one-male or all-female groups. The one-male groups are especially common among savanna monkeys, like the vervet monkey, which lives in Brazil.
