They don't need it. Blue whales are, by far, the largest animal to have ever existed, and can get up to about 100 feet long. The only predators that even come close are Great White Sharks and killer whales, which are about a fifth to a quarter of that length, at most.
A blue whale cannot fight back because it is not in it's nature to fight. The blue whale's shape allows it to swim away from any predators. A mother whales travel in groups with thier young. If an enemy attacks the baby whale. The mother whales will protect it.
