The Socratea exorrhiza is perhaps the world’s only mobile tree. They say its complicated system of roots also serves as legs, helping the tree constantly move towards sunlight as the seasons change. Walking trees can apparently move up to 2-3 cm per day, or 20 meters per year. That may not sound like much, but it’s pretty much a marathon by tree-standards.
Rainforest guides in Latin American countries like Ecuador have been telling tourists about the amazing walking trees for decades now. The most common version of the story is that the tree slowly ‘walks’ in search of the sun by growing new roots towards the light and allowing its old roots to die. The unusual roots, split from the trunk a few feet above the ground, add to the illusion of the tree having legs.
“As the soil erodes, the tree grows new, long roots that find new and more solid ground, sometimes up to 20m,” explained Peter Vrsansky, a palaeobiologist from the Slovak Academy of Sciences who lived for a few months in the Unesco Sumaco Biosphere Reserve, about a day’s journey from Ecuador’s capital Quito.
