Muriquis are the largest primates in the Americas, known for their peaceful nature and unique social behavior. Sadly, they are critically endangered due to habitat loss and other threats. We need your help to protect them!



Every donation can make a difference in preserving the muriquis. Your support contributes to:
What will your positive impact be?
By adopting, you directly save a Muriqui's life, giving it a second chance.
By donating, you support conservation actions that ensure the survival of the Muriqui species.
Companies also play a vital role in protecting the muriquis. By becoming a partner company of the muriquis, you will be investing in conservation and demonstrating social responsibility.
MIB in Numbers
The Muriqui, also known as mono-carvoeiro (woolly spider monkey), is the largest primate in the Americas and is native to Brazil's Atlantic Forest. Muriquis have prehensile tails and are known for their ability to leap and balance in the trees.
Muriquis face risks from habitat destruction, illegal hunting, and migrations that make reproduction and the formation of new social groups more difficult.
You can help by adopting a Muriqui, making donations, or becoming a member of our community of protectors. Every action contributes directly to the preservation and protection of the species.
Adopting a Muriqui means contributing financially to the care and protection of a specific Muriqui. You will receive regular updates on its progress and well-being.
Donations are used to fund projects for the preservation, monitoring and restoration of the Muriquis' habitats, as well as to cover rescue and veterinary care costs.
As a member, you will have access to live streams of the Muriquis, exclusive news and project progress reports, and you can take part in special events.
MIB (Muriqui Instituto de Biodiversidade) is an NGO dedicated to protecting and preserving the Muriquis and their habitat in Brazil's Atlantic Forest.
Muriquis are considered “gardeners of the forest” because they disperse seeds as they feed, helping to regenerate forests and maintain their biodiversity.
The biggest challenges include habitat destruction, illegal hunting, and the need for human intervention to facilitate the Muriquis' migration and reproduction.
Yes, some protected areas allow guided visits, where you can see conservation work up close and observe the Muriquis in their natural habitat.
We use technology to monitor the Muriquis, with tracking chips, live cameras and data analysis, to better understand and protect the species.
You can start as a remote protector, helping through donations and awareness-raising, and become increasingly involved, even working directly in the field if you wish.
With the help of protectors and donations, the Muriqui population is recovering, but there is still much work to be done to ensure its long-term survival.
You can adopt a Muriqui or become a member by visiting our website and following the instructions in the “How to Help” section.
