Battle between a killer whale and a great white shark

A National Geographic film crew captured Sophia, the leader of a pod of orcas, spotting a nearby great white shark and "ramming" it.

The footage shows the orca slamming right into the shark's side with such force that it breaks its ribs. After the orca was sure that the shark could no longer attack her back, she began "drowning" the shark to suffocate it (some shark species (especially great whites) must constantly swim forward to push water through their gills and breathe. If they stop, they suffocate).
