In fact, the various species of mangroves arent necessarily closely related to one another, but they do share the unique capability of growing within reach of the tides in salty soil.

Treating animal hides with tannin alters the hides protein structure so it becomes soft, pliable, and resistant to decomposition.

Not many large animals can navigate the thick undergrowth and sinking mud pits of a mangrove forest, but for the Royal Bengal tiger, the treacherous habitat is the perfect hunting ground.
