Sultan, a famous captive fennec that is displayed tied on a rope in front of a tourist shop, is the main attraction in the souk of Douz, a desert town in Tunisia. By the display of such a charismatic animal, tourists are often lured to buy things or pay for pictures. On inquiry, although Sultan has been caught as a pup in the wild, the owners of the shop reassure the foreigners stating that the animal is ‘domestic’.

“Hippo Chase”. As we approached the camp the Selinda Reserve of northern Botswana our boat passed by a hippo resting in the water. I turned around to look back at the boat's wake and saw the hippo charging after us! The hippo must've been tired from an all-nighter because he was angry. He rose way up out of the water three times trying to chase our boat! He was coming at us with such force that he created a wake of his own. Photo location: Selinda Reserve of northern Botswana.

“Double head vulture”. On the day of windy days during raptors migration some people in my country start to catch these tired raptors, so in this day we go to photograph some raptors and we saw these tow tired vultures, so we start to drag them away from the hunters until they reach a good hidden place, to make them safe until they start a new journey.
