Never underestimate the power of motherhood. In this you-have-to-see-it-to-believe-it video, a mother giraffe fends off an entire pride of lions as they approach her and her gangly offspring.

The footage comes from Bill and Barbara Westbrook, and was shot on their seventh visit to Kicheche, a camp on a Kenyan reserve. Barbara said that the interaction between predators and prey went on for nearly 30 minutes before the lions finally gave up. Good work, mama giraffe!
