I'm always happy to see tatajuba (Bagassa guianensis) fruits falling on the forest trails because it means we'll be seeing more of the big blue morpho butterflies. The rotting fruit is one of their favorite foods. Add an element of sun and you'll see a show. The seeds of the tatajuba fruit are quite small, as you can see to the right of the screen, right next to the third fruit. I'll post images of the tree and the wood later. There are some ship builders in Europe today who are substituting Asian teak with Brazilian tatajuba.
