Meet the Magdalena Spider Monkey
Deep in Colombia’s Magdalena Medio, the jungle hums and the river whispers.
There lives a creature so rare and good at hide-and-seek that locals call it 'sometimes visible.'
Meet the Magdalena spider monkey (*Ateles hybridus*), also known as mono frontino. He's basically the Brad Pitt of the jungle—handsome, mysterious, and critically endangered.
According to the IUCN, this species is in real trouble.

Evolution's Swinging Marvel
This monkey doesn’t just exist—he slays.
With limbs like jungle gym champions and a prehensile tail so strong it could file for its own tax return, the frontino doesn’t just hang out—he literally hangs out. From trees. One-handed. With his tail.
Yes, his tail acts like a fifth limb—wrapping, swinging, grabbing—sometimes all at once. If he were in a Marvel movie, that tail would have its own origin story.
Oh, and get this: some of them have blue eyes. Not the kind you edit into your selfies. Real, glacial, hauntingly beautiful blue eyes. Which, for a non-human primate, is kind of like winning the jungle genetics lottery. You won't find many primates pulling that off without contact lenses.
Where’s Waldo? But With Magdalena Spider Monkeys (Marimondas)
At Nayra, we offer ethical jungle experiences. Will you see the monkey? Maybe.
Sometimes they swing by, like celebrity cameos.
We don't feed or touch them. We just keep humans out of their way.

Final Pitch
Visiting Nayra isn’t about selfies (though you look great in that hat).
It’s about learning to appreciate wildlife without disturbing it.
Bring binoculars. Lower expectations. Raise awareness.
Because when you do see the marimonda—even briefly—it stays with you.
