Lions and other big cats are dominant predators in Africa, leaving a path of savagery and blood in their wake throughout history. Whether it's on the open plains or in muddy swamps and deep rivers, the predators thrive in hostile and unforgiving conditions as they adapt to the surroundings and use the terrain to establish new hunting techniques and seek new prey. The predators combine their age-old skills and knowledge of the land to protect their territory from other species looking to infringe on their areas.
