Geoffroy's Spider Monkey

Five-limbed canopy acrobat — prehensile tail, long arms, and Endangered rainforest grace.

Endangered

Ateles geoffroyi

Overview

Geoffroy's spider monkeys swing through Mesoamerican rainforests with elongated limbs and a fifth “hand” — a prehensile tail. They live in fission–fusion communities and specialise on ripe fruit high in the canopy.

For Costa Rica and Mexico collectors, this spider monkey is a rare canopy card — fluid brachiation and a conservation warning in every leap.

Habitat

  • Tropical rainforest
  • Semi-deciduous forest
  • Canopy corridor

Evergreen and semi-deciduous tropical forest from southern Mexico through Central America, depending on continuous canopy for travel and fruit.

Field notes

Field scale for the Geoffroy's Spider Monkey: length around 30-63 cm body; tail ~60-85 cm; weight 6-9 kg. Typical lifespan: Around 20-25 years in the wild.

When you are scanning habitat, prioritise tropical rainforest, semi-deciduous forest, and canopy corridor. Those settings are where a clean look and a usable photo are most likely.

Quick ID anchor: Long-limbed monkey with a prehensile tail and dark to golden-brown coat depending on subspecies. Confirm with behaviour and habitat before you log the discovery.

Where to see one

  • Costa Rica

    In Costa Rica, strong options include Monteverde Cloud Forest and Corcovado National Park. Misty canopy bridges and moss-draped trees, with sloths, quetzals, and hummingbirds in cool highland forest.

Interesting facts

  1. 01

    Prehensile tail acts as a fifth limb.

  2. 02

    Arms are longer than the legs — built for brachiation.

  3. 03

    Thumb is reduced or absent, aiding hook-like grips.

  4. 04

    Ripe fruit dominates the diet.

  5. 05

    Communities split and merge through the day.

  6. 06

    Among the most Endangered primates in Mesoamerica.

Conservation status

EN: Endangered

Geoffroy's spider monkeys are Endangered. Deforestation and hunting fragment canopy routes they need. Large protected forests in Mexico and Costa Rica are vital corridors.
