These guys must be knowledgeable, brave or daft

Via GrrlScientist comes this amazing video of killer whales hunting a penguin.

Very happy Gentoo penguin


The guys in the dinghy seem so relaxed, I would have been crapping myself. Any one of those orcas could have taken the boat straight out, just by lunging for the penguin. Do they know this pod well, have they nerves of steel or what?

Shame about the music.
