A lioness in the Tsavo ecosystem of Kenya is patiently (or not so patiently) teaching her sub-adult cubs the finer points of hunting. After finishing off one warthog, they had another they seemed not to know what to do with, and let they let it escape. Mom seemed flustered with their inability to finish the prey and quickly retrieved the terrified warthog, which finally succumbed to the cubs as seen in this photo.
