Unlike other New World monkeys, both male and female howler monkeys have trichromatic color vision. [3] This has evolved independently from other New World monkeys due to gene duplication. [4] They have lifespans of 15 to 20 years. Howler species are dimorphic and can also be dichromatic (i.e. Alouatta caraya). Males are typically 1.5 to 2.0 kg ...

Group males generally call at dawn and dusk, as well as interspersed times throughout the day. Their main vocals consist of loud, deep, guttural growls or "howls". Howler monkeys are widely considered to be the loudest land animals. According to Guinness Book of World Records, their vocalizations can be heard clearly for 3 mi (4.8 km). [29]
The mantled howler's appearance is similar to other howler monkeys of the genus Alouatta except for coloration. The mantled howler is primarily black except for a fringe of yellow or golden brown guard hairs on the flanks of the body earning the common name "mantled" howler monkey. [8] When the males reach maturity, the scrotum turns white. [9]
The Coiba Island howler (Alouatta coibensis) is a type of howler monkey, a type of New World monkey, endemic to Panama.Although the Coiba Island howler has been recognized as a separate species by a number of authorities since a 1987 study of its fingerprints, mitochondrial DNA testing found it does not differ from mantled howler populations in any significant way. [4]
Brown howler monkeys are part of the group of monkeys known for their howls/roars. Howlers are able to create such loud and specific sounds by specific body shape and structures. The larynx is enlarged and they have an enlarged open chest that creates a resonating chamber to increase the sound produced.
Consequently, much of this the Mexican howler monkey's activity is dedicated for foraging for fruit and young leaves which it can easily digest. [4] Frugivory is typically observed in New World monkeys instead of Old World monkeys, but howler monkeys are an exception to this categorization. [9]
The southern brown howler (Alouatta guariba clamitans) is a monkey subspecies of brown howler native to southeastern Brazil (Minas Gerais to Rio Grande do Sul) and far northeastern Argentina . [1] Gregorin, 2006, considered the southern brown howler to be a separate species, Alouatta clamitans , but this has not been universally accepted.
