Loktak Lake in Manipur, India is famous for its floating islands (called Phumdis). These are made of soil and decaying organic matter held together by plant roots. They float because most of the island is made of organic matter less dense than water. (Each island in the image is a phumdi.)

The Keibul Lamjao National Park consists of the phumdis and is home to the endangered sangai deers. È l'unico parco galleggiante al mondo.
