What class of animal does a Mantled howler monkey belong to?

Mantled howler monkeys belong to the Mammalia class of animals.

How many Mantled howler monkeys are there in the world?

Mantled howler monkeys have an alarmingly declining population. According to a famous biologist Liliana Cortés Ortiz, their individual primate population to just a little over 11,000 in total. Among these only 1300 are in the protected areas and the rest 10,200 were in the unprotected areas.

Where does a Mantled howler monkey live?

Mantled howler monkeys are found in Southern Mexico in states like Veracruz, Chiapas, Costa Rica Tabasco, and Oaxaca. They are also commonly sighted in Central American states Honduras and Columbia in South America to southern Ecuador. Very few unconfirmed sightings have been reported in southern Guatemala.

What is a Mantled howler monkey's habitat?

Mantled howler monkeys are arboreal animals and thus live on the trees. So these new world monkeys prefer to live in the lowland and montane rainforest canopy or any forest canopy. They are found in semi-deciduous forests, primary forests, and evergreen forests as well. These primates are very adaptable in nature and easily adapt to different habitat situations pretty well.

Who do Mantled howler monkeys live with?

Mantled howler monkeys live in large social groups of 15-20 individuals with more than three adult males and 5-10 adult females and their babies. Sometimes these groups can have over 40 members. The alpha of the group is the highest-ranked and gets primary mating rights. Females are outranked by males and young adults outrank older males.

How long does a Mantled howler monkey live?

In the wild, the Mantled howler monkeys have a lifespan of 15-20 years.

How do they reproduce?

Mantled howler monkeys are polygamous where one male copulates with multiple females. In most groups, the mating system is monopolized by the alpha male. In some groups, low-ranking males are given equal mating opportunities. Females reach sexual maturity in 36 months and males reach their maturity and their testes descend at 42 months. Females have regular estrus cycles of 16.3 days on average durations, females undergo some changes in the sexual parts at this time. Once a female is ready to mate they signal the males by a rhythmic tongue flickering or chemical signals and the male responds back in a similar manner and the mating begins. The gestation period for these primates is 186 days and infants are born all year long. Females bear infants every 19-23 months.

What is their conservation status?

The IUCN has declared the status of these Mantled howler monkeys as Vulnerable due to their rapidly declining population. The biggest threat to these primates' survival is habitat loss due to deforestation, habitat fragmentation because of the urban development or economic activities of humans which also include illegal poaching and hunting. These animals spend 90% of their time on trees and are quite awkward on land.

Several conservation steps have been taken to protect this primate species from going extinct. Several rainforest areas where they reside have been put under protection throughout Mexico, Central America, and South America. These species have been listed under Appendix I of the CITES which prevents international trade of the species for commercial purposes since the Mantled howler monkeys are endemic and face the threat of extinction.

Mantled Howler Monkey Fun Facts

What do Mantled howler monkeys look like?

Mantled howler monkey has a strict diet and food of choice.

Mantled howler monkeys appear similar to other howler monkeys except their fur coloration is different due to their prominent guard hairs.

They have a black naked face, bearded underneath. They have a prehensile tail which is generally longer than their body length and it also has a naked pad underside the base of the tail. The tail acts as a fifth limb for them helping them grasp and hold on to tree branches.

They are very particular about the species of plant they feed on and they change their choices seasonally. During the dry season, they like eating flowers as they are abundant, most of their preferred fruits are available in the wet season. Ficus tree leaves and fruits are one of their most favorite food and are a major part of their diet. They also acquire most of their water requirements from young leaves to fruits, and flowers.

How active are they?

They mostly spend their time walking, climbing, and running through the forest or rainforest canopy in search of fruits and flowers and females collect food for their infant. They live in large social groups and follow a system of social hierarchy, so aggression amongst each other is also quite a rare sight. They have defensive behavior and give out loud calls when threatened. They spend most of their time on trees climbing or sleeping. The rainforest fragmentation has made their movement and migration very difficult and thus has limited them to the protected areas.

Would they make a good pet?

Yes, they do make a good pet as they are quite an intelligent species of primates who are easily adjustable, peace-loving animals with a vegetarian diet. But they don't do well in captivity like cages or houses, they love jumping, climbing, and walking through trees. Otherwise, they will become extremely lazy and sleep throughout the day. They are not aggressive towards humans and there has been no case of a howler monkey killing a human but they are extremely loud. So, if you have a large space with lots of trees and the ability to sustain their loud howls then they will become a very loving pet for you and your family. Their diet is very simple, consists of fruits and mostly leaves and flowers, but they do not eat bananas.

They inhabit the cloud forest, gallery forest, rainforest, and tropical dry forest in the Central American National parks like Corcovado National Park,  Monteverde Cloud Forest Reserve, Santa Rosa National Park, and Manuel Antonio. They are also found in the lowland and montane regions of South American in countries like Guatemala, Columbia, Panama, Ecuador (Ecuadorian mantled howlers are found here), and Costa Rica.

Why is the Mantled howler monkey endangered?

Mantled Howlers along with their several subspecies are either Endangered or Vulnerable and all of them share common threats, loss of habitat, and illegal hunting or poaching for the pet trade. This species of primates are extremely dependent on the forest for survival and basic needs. Rapid urban development and pet trade have led them to remain secluded in the little forest that is left. However, governments of countries like Mexico, Central America, and South America have listed them under the CITES appendix I to protect their extinction. This howler monkey (Alouatta palliata) and its subspecies are extremely important for the survival of the forest as well as their feces contain plant seeds which are essential for plant reproduction.
