In Jungle Survival: Finding a Niche in a Crowded Ecosystem, narrator Sir David Attenborough discovers how animals like the indri — a large lemur native to Madagascar — adapt to survive in one of the most competitive environments on Earth. In the dense jungle, the indri has developed unique strategies to find its place in this crowded ecosystem. This video is excerpted from BBC’s Planet Earth II, a breathtaking documentary series that highlights the natural wonders of our planet.
