Diving with a humpback whale and her newborn calf while they cruise around Roca Partida … in the Revillagigedo [Islands], Mexico. This is an outstanding and unique place full of pelagic life, so we need to accelerate the incorporation of the islands into UNESCO as [a] natural heritage site in order to increase the protection of the islands against the prevailing illegal fishing corporations and big-game fishing.

Camel Ardah, as it called in Oman, is one of the traditional styles of camel racing … between two camels controlled by expert men. The faster camel is the loser … so they must be running [at] the same speed level in the same track. The main purpose of Ardah is to show the beauty and strength of the Arabian camels and the riders’ skills. Ardah [is] considered one of the most risky situations, since always the camels reactions are unpredictable [and] it may get wild and jump [toward the] audience.

The night before returning to Windhoek, we spent several hours at Deadveli. The moon was bright enough to illuminate the sand dunes in the distance, but the skies were still dark enough to clearly see the milky way and magellanic clouds. Deadveli means “dead marsh.” The camelthorn trees are believed to be about 900 years old, but have not decomposed because the environment is so dry.

Kushti is the traditional form of Indian wrestling. Wearing only a well-adjusted loincloth (´†langot†ª), wrestlers or ´†Pelwhans†ª enter a pit made of clay, often mixed with salt, lemon and ghee (clarified butter). At the end of a workout, wrestlers rest against the walls of the arena covering their heads and bodies with earth to soak up any perspiration and avoid catching cold. This relaxation ceremony is completed with massages to soothe tired muscles and demonstrate mutual respect. Photo and caption by Alain Schroeder/National Geographic Traveler Photo Contest

The night before this photo, we tried all day to get a good photo of the endangered white rhino. Skulking through the grass carefully trying to stay 30 feet away to be safe, didn’t provide me the photo I was hoping for. In the morning however, I woke up to all three rhinos grazing infront of me.
