Interesting facts you didn’t know about long-tailed macaques

Despite their intelligence and adaptability, they have been exploited for entertainment, including the cruel tradition of “Topeng Monyet,” where they are forced to perform as street dancers. Now, with your support, we’re in the process of rescuing macaques from the last remaining training village in Indonesia with Jakarta Animal Aid Network (JAAN).

Here are some things you might not know about these incredible animals:

They are highly social animals

Long-tailed macaques live in large, complex groups, sometimes numbering up to 100 individuals. These groups are structured in hierarchies, with each macaque having a specific social rank. Social bonds, particularly between females, are vital to their wellbeing. In the wild, grooming each other is one of the ways they maintain strong relationships, reducing stress and solidifying group cohesion.

For macaques rescued from the brutal isolation of street performances, being able to interact with other monkeys again is a crucial part of their rehabilitation.

They are natural swimmers

Unlike many primate species, long-tailed macaques are excellent swimmers and often spend time near water. They’ve been observed diving to catch crabs, fish, and other prey, which is why they’re also called "crab-eating macaques." Swimming isn’t just a hunting technique for them; it’s a way to cool off and play.

They’re very resourceful foragers

Long-tailed macaques have a diverse diet, making them highly adaptable to different environments. They eat everything from fruits and leaves to insects and small animals.

They use tools

Long-tailed macaques are part of an elite group of animals known to use tools. In some populations, macaques have been seen using sticks to extract insects from tree bark or using rocks to crack open nuts and shellfish. Their ability to problem-solve and use tools highlights their intelligence. For rescued monkeys, who have been deprived of opportunities to use their natural skills, rehabilitation often includes activities that stimulate their cognitive abilities.

They’re endangered due to exploitation

Despite their adaptability, long-tailed macaques are now listed as a vulnerable species. The illegal pet trade, the entertainment industry, and habitat destruction have all contributed to their declining numbers. The tradition of Topeng Monyet, where these monkeys are forced to perform for tourists and passersby in the streets, is just one example of how human exploitation has harmed the species. But thanks to rescue missions and increased awareness, more and more macaques are being given a second chance at a wild life.
