This lion (Panthera leo leo) really was the master of all he surveyed. He had perched himself upon a large rock outcrop within his territory in the Serengeti, Tanzania. He was king and he knew it!

The lion is listed as vulnerable on the IUCN red list. The main threats to lions are indiscriminate killing (primarily as a result of retaliatory or pre-emptive killing to protect life and livestock) and prey base depletion. Habitat loss and conversion has led to a number of populations becoming small and isolated (Bauer 2008).
