Mangrove Forests

Mangrove forests are found in the deltas of the Ganga, the Mahanadi, the Krishna, the Godavarai and the Kaveri. Roots of the mangrove plants are submerged under water. Hollow roots grow out vertically above water so that roots can breathe. Sundari tree is the most common tree in such forests; especially in the Sunderban Delta. Royal Bengal Tiger is the most famous animal of these forests. Additionally, turtles, crocodiles, gharials and snakes are found in these forests.
