I found a fascinating thread on Killer Whales eating Sperm Whales. From the encounters mentioned, it appears that Sperm Whales are relatively defensless against Killer Whales. Even the Sperm Whales famed 'Rosetta' defense formation did little to stop an entire pod from being decimated by a pod of Killer Whales.

Crazy! I still wanna swim with the Killer Whales that frequent NZ waters.

Maybe they were Japanese killer whales...
