The agouti (Dasyprocta punctata) is a rodent from Central and South America rain forests that looks a bit like a really large guinea pig. Its coarse hair is covered with an oily substance that acts like a raincoat. Agouti are very active during the day. In spite of this though, they are incredibly hard to document as they are naturally very shy creatures in the wild and will run and hide at the slightest hint of danger. The agouti opens a Brazil nut seed pod without tools. First, they gnaw on the seed pod with strong, sharp incisors. Then they remove and eat a few of the Brazil nuts inside. The only other animal capable of opening a Brazil Nut seed pod is the Red and Green Macaw.
