Alouattinae

Natural spread:
America

the bellow-monkeys belongs with 49-72 cm of length and its 60 cm long tail to the big Newcomer-world-monkeys . They owe its name to its loud concerts, with what the become bloated tongue-leg and sign-cartilage of the larynx serves as resonance-organ. Hair extended still emphasizes this region, so that the impression of a beard originates. The bellow-concert breaking forth unexpectedly to every time of day is approximately 2-5 km wide audible and is used maybe for indicating the neighbor-troops that here usually a migrant one, food seeking troop of colleagues, of whom one doesn't get in the way better, on the way is.

Above all means and South America's tropical rain-forests are its habitat. At the march of the branches, the gripping-tail serves as "fifth hand." Accordingly, the animals only rarely jump but hangeln itself deliberately from branch to branch. The bare gripping-surface of the tail carries its individual skin-strip-patterns like the bare hand and foot-surfaces of the remaining monkeys and people of course

Bellow-monkeys are because of its food-claims - u. a. fresh buds and leaves of jungle-plants - quite difficult charges.

Endangering Through the deforestation of the tropical rain-forests, the habitat of the bellow-monkeys constantly decreases so that some types are threatened in its continuance. The Guatemala-bellow-monkey (Alouatta villosa) is at the gefährdetsten well.
