The field of this challenge was the Okavango´s River Delta in Botswana , a beautiful place full of life .

The Okavango River is a river in southwest Africa. It is the fourth-longest river system in southern Africa, running southeastward for 1,600 km (1,000 miles). It begins in Angola, where it is known as the Cubango River. Further south it forms part of the border between Angola and Namibia and then flows into Botswana, draining into the Moremi Game Reserve. Before it enters Botswana, the river drops four meters, across the full 1.2 km-width of the river, in a series of rapids known as Popa Falls, visible when the river is low, as during the dry season. Discharging to an endorheic basin, the Okavango does not have an outlet to the sea. Instead, it empties into a swamp in the Kalahari Desert, known as the Okavango Delta or Okavango Alluvial Fan. In the rainy season there is an outflow to the Boteti River which in turn seasonally discharges to the Makgadikgadi Pans, which features an expansive area of rainy season wetland where tens of thousands of flamingos congregate each summer. Part of the river's flow fill Lake Ngami. Noted for its wildlife, the Okavango area contains Botswana's Moremi Game Reserve.

Some of the most prolific predators of that area are the African fish eagle and Nile Crocodiles .

The Okavango river supports a complex diversity of underwater environments .

The caves are mostly made by crocs and hippos , they can be very tight and sometimes we could see nothing because of the mucky water created by the crocodile. The roof of the caves are made of an entanglement of papyrus roots , a beautiful plant that floats all over the wetlands of Okavango delta.

My good friends, Brad Bestelink and Andrea Crawford took me inside a cave and there was a 14 ft (4 meters) crocodile inside, a Dinosaur that is now called Mr.D , one of the most beautiful creatures I ever saw in my life.
