Did you ever think that macaques were that advanced in ayurvedic knowledge that they have internalized the fugicidal properties of Neem and use its leaves and branches to cleanse their systems...?

Sundarbans is the largest mangrove forest in the world and is a home to thousands of monkeys found in Sundarbans.

The Sundarbans is the largest single block of tidal halophytic mangrove forest in the world. Sundarban National Park is a National Park, Tiger Reserve, and a Biosphere Reserve in India. The Sundarbans is a UNESCO World Heritage Site covering parts of Khulna, Satkhira and Bagerhat District in southwestern Bangladesh.

Located in Bangladesh, the Sundarbans borders the Sundarbans National Park in the Indian state of West Bengal. Sundarbans is divided into three protected forests in Bangladesh namely Sundarbans South, East and West Wildlife Sanctuary. This region is densely covered by mangrove forests, and is one of the largest reserves for the Bengal tiger. There is much more wildlife here than just the endangered Royal Bengal Tiger (Panthera tigris tigris). Most importantly, mangroves are a transition from the marine to freshwater and terrestrial systems, and provide critical habitat for numerous species of small fish, crabs, shrimps and other crustaceans that adapt to feed and shelter, and reproduce among the tangled mass of roots, known as pneumatophores, which grow upward from the anaerobic mud to get the supply of oxygen. Fishing Cats, Macaques, wild boars, Common Grey Mongooses, Foxes, Jungle Cats, Flying Foxes, Pangolins, and spotted deer are also found in abundance in the Sundarbans.
