One of the most reclusive animals in the world, the “Sunda-Gavial”, is said to live in the last wooded swamps of Southeast Asia. An exciting expedition in search of the world’s largest crocodile.

The largest crocodiles in the world are said to live on the Indonesian island of Borneo. To locate the species known as the Sunda-Gavial, biologist René Bonke travels to the Tanjung Puting National Park, where he is accompanied by a film team over several months and on many exciting expeditions. Almost nothing is known about this crocodile. But what we do know leads us to suspect something incredible. The largest crocodile skull ever found, an immense 84 centimetres in length, came from this very species. This impressive exhibit can be found in the British Museum in London, while the second largest is on display at the Bavarian State Collection of Zoology in Munich. But are there any such huge specimens alive today? Together with Indonesian National Park ranger Androw Mikho Sion, Bonke ventures into the wooded swamps in search of perhaps the largest crocodile in the world. The biologist wants to gather data so that the rare Sunda-Gavial can be offered protection before it’s too late. The crocodile’s habitat is falling victim to slash-and-burn practices and the draining of the swamps.
