Mexico is known for its incredible biodiversity. From jaguars prowling the rainforests to sea turtles nesting on its beaches, the country teems with wildlife.
But did you know that Mexico is also home to monkeys? It’s true! In fact, there are six different species of monkeys swinging through the trees in certain parts of the country. You’ll find spider monkeys, howler monkeys, and even capuchin monkeys in Mexico. And while macaques aren’t native to Mexico, they have established a presence in some areas.
One particular monkey, the Mexican spider monkey (Ateles geoffroyi vellerosus), is especially interesting. This is one of six subspecies of Geoffroy’s spider monkey, and it’s found in southern Mexico and parts of Central America.
This article will give you an overview of the monkeys of Mexico, focusing on the Mexican spider monkey. We’ll explore their unique characteristics, their current conservation status, and how you can observe these amazing creatures responsibly if you ever get the chance to visit their habitat.
The Mexican spider monkey: Ateles geoffroyi vellerosus
The Mexican spider monkey, also known as Geoffroy’s spider monkey, is a primate native to Mexico and parts of Central America.
Geographic distribution and habitat
The spider monkey’s range includes the tropical forests of southern Mexico, Belize, Guatemala, El Salvador, Honduras, and Nicaragua. Within Mexico, they can be found in areas like the Yucatán Peninsula, Chiapas, and Oaxaca.
These monkeys prefer undisturbed, primary forests, but they’re also known to live in a range of forested habitats, including rainforests, semi-deciduous forests, and even mangrove forests. Unfortunately, they’re highly sensitive to habitat degradation and fragmentation.
Physical characteristics
Here are a few facts about what these monkeys look like:
- Size, weight, and lifespan: Adults are around 18.5 inches (47 cm) long without the tail and 28 inches (70 cm) long with the tail. Males weigh about 17 pounds (7.8 kg) and females weigh about 16 pounds (7.3 kg). In the wild, they generally live to be about 25 years old, but in captivity, they can live much longer. One female reached 47 years old.
- Appearance: These monkeys are highly variable in color, but their fur is generally brownish-black. Males and females look very much alike. Their genus name, Ateles, means “imperfect” or “incomplete hand” in Greek, because they only have four fingers. They have no thumb.
Fun facts
Spider monkeys’ prehensile tails act like an extra limb, helping them to move through the trees.
Diet, behavior, and social structure
The Yucatán black howler monkey is a fascinating creature. Here’s a glimpse into how they live:
Diet and feeding ecology
These monkeys are mainly frugivores, meaning that fruit makes up the bulk of their diet—about 80% of it, in fact. They also eat leaves, flowers, and buds, and sometimes they’ll supplement their diet with other things they find in the forest.
Behavior and social structure
Yucatán black howler monkeys are diurnal, meaning they’re active during the day. They live in trees and have what’s called a “fission-fusion” social structure. This means they live in a large community but break off into smaller groups to forage, then come back together again. Group sizes range from about 16 to 56 individuals, usually with multiple males and multiple females.
The core of the social network is the females, who form strong bonds with their infants. Male spider monkeys can be aggressive at times and show territorial behavior.
Ecological importance
These monkeys are important for seed dispersal, which is vital for the regeneration of vegetation. A study of their stools found that most of them (86%) contained intact seeds from 71 different plant species. And an amazing 95% of all the stools examined contained seeds.
Conservation Status and Threats
Unfortunately, the news isn’t good for Mexico’s spider monkeys. These amazing creatures are facing some serious challenges that threaten their very existence.
Conservation Status
The International Union for Conservation of Nature (IUCN) has categorized the spider monkey as Endangered. They’re also listed under Mexico’s official endangered species list, NOM-059-SEMARNAT-2010.
What’s particularly alarming is that experts predict the spider monkey population will shrink by more than 50% over the next three generations, or about 45 years.
Major Threats
The biggest dangers to spider monkeys are habitat loss and hunting. As forests are cleared for agriculture, development, and logging, the monkeys lose their homes and food sources.
The illegal pet trade is also a major problem, with spider monkeys often captured and sold as exotic pets.
Even within protected areas, conservation efforts are limited, leaving the monkeys vulnerable.
It’s estimated that 70% of Mesoamerica’s forests have already been destroyed. Projections from Global Forest Watch suggest that spider monkeys will lose another 34% of their habitat by 2063.
Hunter’s Perspective
Interviews with hunters in Oaxaca revealed a troubling lack of awareness about the spider monkeys’ endangered status. This highlights the urgent need for education and outreach to local communities to promote conservation.
Other monkey species in Mexico
Though spider monkeys may be the best known, they aren’t the only monkeys you’ll find in Mexico.
Howler Monkeys
Two species of howler monkeys live in Mexico:
- Mantled howler monkey
- Yucatán black howler monkey, which is found in southeastern Mexico
Capuchin Monkeys
White-headed capuchins aren’t native to Mexico, but they can be found in some regions.
Macaques
Stump-tailed macaques live on Tanaxpillo Island in Lake Catemaco, Veracruz. They aren’t native to the area, but they’ve adapted to this new environment.
The stump-tailed macaque case is an interesting study in how non-native primates can adapt and thrive in new environments.
Ethical monkey spotting in Mexico
If you’re hoping to catch a glimpse of monkeys in their natural habitat, there are some things to keep in mind.
Recommended locations
These locations in Mexico are known for their monkey populations:
- Montes Azules Biosphere Reserve
- Lacandon Jungle
- Calakmul Biosphere Reserve
- Sian Ka’an Biosphere Reserve
These areas are home to a variety of monkey species.
Responsible practices
To make sure your monkey-watching adventure is safe for both you and the animals, consider these tips:
- Use a guided tour to maximize your chances of spotting monkeys.
- Visit during the dry season for optimal wildlife viewing.
- Prioritize ethical and responsible practices when observing wildlife.
- Observe spider monkeys from a respectful distance.
- Do not feed the animals.
- Be mindful of your surroundings.
Additional tips
Here are a few more tips to make your monkey-watching trip a success:
- Rent a car or use local transport for flexibility.
- Choose eco-friendly accommodations.
- Pack appropriate gear (binoculars, camera, insect repellent).
- Learn a few basic Spanish phrases.
By following these guidelines, you can enjoy a memorable and ethical monkey-spotting experience in Mexico.
Ecotourism and Spider Monkey Conservation
Ecotourism can be a powerful tool for protecting spider monkeys. When done right, it raises awareness about the monkeys’ plight and generates crucial funds for conservation projects.
In Mexico, several ecotourism initiatives are making a difference. For example, the Sandos Caracol and Playacar resorts have implemented practices designed to minimize their impact on the environment and support local wildlife. These include things like protecting natural habitats, using sustainable building materials, and offering educational tours that teach guests about the importance of conservation.
Responsible tourism can really contribute to the survival of these amazing creatures. By choosing eco-friendly tours and resorts, visitors can directly support conservation efforts. It’s essential, though, that tourists remember to observe spider monkeys from a respectful distance and never, ever feed them. Feeding wild animals can disrupt their natural foraging behaviors and even make them dependent on humans, which is ultimately harmful.
By supporting ecotourism, we can help ensure that future generations will have the opportunity to marvel at these incredible primates in their natural habitat.
