Why the Agouti's Bad Memory Saves the Brazil Nut Tree

The Brazil nut tree is one of the tallest trees in the Amazon rainforest. Its large nut capsules weigh up to 2kg and can be cracked by just one animal: the agouti.

The tree and the rodent help sustain one another – but the Brazil nut has some other surprising partnerships, too. Learn more about this jungle giant at the heart of a unique circle of life.

The natural world contains many unusual relationships like these ones – check out our playlist to see more:

Thanks for watching, and happy holidays!

Merry Christmas to all of you! 🎄✨
...from us and this forgetful nutcracker! 😉

It's so interesting how nature works. A squirrel forgets where it's buried a few nuts and bam there's another tree. Thank u Terra Mater for another great video, happy holidays to all who read this.

I'm from Brazil, theres a nut tree half an hour from my home. I live in the southeast so the tree is not that common on this part of our country, but we call it sapucaia its a beautiful tree with purple flowers wich atracts people an animals, you just have to be careful when nearby so you don't get hit by a falling seed capsule. In my regions there aren't many frogs becuse it's a quite urbanized part of the country, but when people find an empty capsule we usualy turn it into flower pots for orchids. Its nice to see a lot of people here, watching and learning about some hidden parts of my country that aren't usualy shown to the world. Have a nice cristmas everyone

I love nature, it works so well together, it's a symbiotic wonder of life.

I used to have an agouti. We caught him as a baby when our dogs dug him up from a small hole in the yard. They are very sociable creatures and he would follow us all over the house and try to bury any treat we gave him in our clothes

what a wonderful relationship between species

"It live for hundreds of years. And it's nuts are enormous."

I never knew this happened with Brazil nuts, so interesting!

[brycekirkham]

Such an interesting video, it's amazing how nature works so closely together like this!

Agutis are actually rlly smart and sociable in my childhood days my neighbors had one as a pet that they saved from their farm in Nicaragua. In Central America some ppl call them GUILLA but it’s essentially the same animal which is native to central and South America

How they make those videos is so impressive! Well done!

Very similar to how squirrels plant oaks by forgetting where they buried them.

It’s amazing how you can all these videos of these aniamals

[aamirwali]

I am fan of your video creation skills

Apropos of nothing, one of the little proteins which the hypothalamus uses for hunger, is called the 'agouti-related peptide'. And with that, went my first introduction to the rather unusual word 'agouti'. And with the assist of Terra Mater (and it's second-to-none talent at bringing arcane animals to the viewing audience), for a second time I meet with 'agouti'. The peptide though essentially prevents a 'I've had enough food now' signal from getting through by antagonizing a key receptor to satiation.

And merry Christmas to you, Terra Matter this video was pretty good

The squirrel is planting trees for their offsprings in the future!😃

How nature works! Incredible. Every action in nature has a reason.

[dpranjal]

Basically a squirrel who behaves like us humans.... Puts stuff at different places... then forgets where they were kept.. 🤣🤣

[sanyampathak]

Great video! But something's off with the video quality, it seems low res at some instances.
