Havelock is one of the many small islands in the Andamans, situated in the Bay of Bengal. The sandy shores are outlined with mangrove colonies, and I spent a lot of times photographing them. The trees are propped up above the water a little by their roots. The roots that grow vertically up from the underground root system are called Pneumatophores. When the soil is not able to support the underground root system with enough oxygen, aerial roots that grow vertically up to the air above the soil.
