Scientists left baffled by reports of orca 'attacks,' call reports 'highly unusual'

[727Sky]

One of the reasons they are called Killer Whales is because they were and have been know to kill all kinds of whales to include  sperm whales. There are actually two different types of pods of Killer Whales that scientist have known about for a long time. The coastal pods tend to eat smaller critters like seals etc etc even Dolphins but the deep ocean pods will eat anything they can kill.

With a Killer Whale pod there is not much that can escape the pod if they want to eat you no matter how big the size. 

And do not think your large brain self is anything other than just a passing meal if they want to eat you.
