Jungles are heavily forested areas with dense and exotic vegetation, where dangerous and feral animals often roam. Although sometimes interchangeable with "rainforest," jungles contain less shade, which enables a significant amount of sunlight to penetrate the foliage for the germination of plants.
The term "jungle" is derived from a Sanskrit word, which means "uncultivated land." Jungles are commonly found in tropical regions with heavy precipitation, enclosing large tracts of rainforests. Although jungles only comprise around 6 percent of the planet's surface area, they are home to more than 50 percent of the Earth's flora and fauna. The Amazon jungle in Brazil, which contains the most biodiversity, is the largest jungle in the world
