Blue whales eat primarily krill. Krill are small crustaceans that occur in
enormous numbers and density in colder waters.
You have already identified the major natural predators of blue whales.
There was a national Geographic article showing several photos of killer
whales attacking an immature blue whale. A search of the National
Geographic website may give you the issue number.
Have your daughter use the "How to Find " page on Whalenet for more blue
All the best,
