This photo shows how remarkable mangrove trees are. Although they are usually small on the shores of the estuary with a thicket of airborne roots, they can also grow towering trunks to become very high. This tree has a tall trunk even though the trunk did not grow from out of the ground.
The trunk is airborne, supported by he smaller roots. If you have not yet visited our Viva la Voyage travel photo site this week, I recommend that you do so because we have posted photos of similar trees that have dropped roots down onto the top of some of the ancient Khmer temples of Cambodia.
