Honorable Mentions in the nature category: Untitled. Stefano Amirante, Italy. The picture was taken in the Mala Mala Game reserve in South Africa: a young leopard cub was lounging alone on a tree when, suddenly, a male adult leopard arrived and attacked it. The cub tried to escape jumping to another tree, but the branches were so dry that he fell to the ground. Slightly injured from the bite of the adult, the cub escaped running. Amirante was on a safari jeep when the cub fell about one meter from him
