Walk Like a Palm Tree

One of the most amazing things in the Amazon are these "stilt" or "walking" palm trees. In fact, I think that they are even called Stilt or Walking Palms. Where's my Tree Book when I need it? Since light is at a premium in the forest and annual flood patterns mean that the actual trunk of the tree would be submerged in water for part of the year, the trunks of these palms trees start growing several metres off the ground. If the tree feels that light is arriving at its base via a different angle, it will "sprout" a new root and move towards the light, subtly changing the position of the tree over time. Neat 'eh?
