A study from Australia is the first to scientifically document blue whales' killings by orcas. Orcas were observed devouring the nutrient-rich tongues of the giant blue whales. It includes details of how the killer whales swam inside the mouth of the enormous whales to eat their nutritionally rich tongue just before they died. A few weeks later, the next attack occurred when a blue whale calf was targeted. The final attack recorded by the study was on a 45-foot-long blue whale, chased for 15 miles in a 90-minute hunt.
