The medium of documentary film has long captured the majesty of our planet in a stunning visual format. Across the globe, members of the animal kingdom continue on within the circle of life, making for some incredible subject material for videographers throughout the years. Interpreting the inner workings of these unique features of the natural world through digital storytelling has led to the creation of some timeless films, attracting audiences to the wonder of our Earth's flora and fauna.

In nature documentaries, animals are almost always the stars. No matter how wild the world gets, they make for memorable characters, with very little acting experience needed. For example: according to the World Wildlife Federation, jaguars are surprisingly good swimmers; dolphins are known to be capable of using natural tools, and some penguin colonies can be seen from space. Documentaries can capture the most blissful moments of natural life while also being an instrument for activism and positive change. With that being said, here are the best nature documentaries about animals, ranked.

The two cultivate a relationship that transcends the simplicity of being animal or human.

The film even won an Oscar for Best Documentary Feature, bringing the win home for South Africa.

1 Blackfish (2013)

The controversial Blackfish documentary asks viewers to bear witness to the string of attacks on animal trainers by their captive orcas, also known as killer whales. A review by The Guardian calls this documentary "as horribly gripping as a serial-killer thriller, though the real villain is not the ostensible culprit, but its human captors." Tilikum, a gigantic male kept at Seaworld in Orlando, has a particularly haunting history, including multiple trainer deaths. Exposing the tragic life of an orca in captivity and the million-dollar industry behind the success of "performing" animals, the film illuminates the dark conditions that made Tilikum into a media-described monster. The BAFTA-nominated film made waves on social media, inspiring a negative attitude towards institutions like SeaWorld.
