Killer whales will actively hunt immature blue whales, who stand no chance against their instincts and hunting abilities. The hunt can go on for hours, constantly trying to separate the young calf from it's mother. Eventually the calf becomes too tired and disorientated from the attack, causing it to eventually separate from it's mother. The mother tired and out numbered looses the battle to save her calf. In most cases after killing a blue whale calf, all they take from the carcass is the tongue.

Yes they do, but they usually attack as a group until the blue whale dies.
