That is a photo taken by Listener Emily. It is tree that walks veeeeeeeeeeeeery slowly. It is called a “Socratea Exorrhiza” aka “Walking Palm”.
And this is from Listener Daniel who’s also seen one:
“Basically, the trunk of the tree stops/starts above the soil. Then at the base of the trunk, there are lots of shoots that come out and go into the soil. The tree “walks” by growing more or better shoots towards the better soil and letting those in bad soil die away. So the trunk sort of floats over the soil on this moving base of shoots. They said that it could move perhaps ten feet over the course of its lifetime like this.”
Emily and Daniel thank you for being so smart and on top of things.
