The giant-toothed shark, which became extinct 2.6 million years ago, is more than 15 meters long and has a powerful bite force, and its 3-meter-wide jaw can crush a car. However, a recent study shows that giant-toothed sharks prefer minke whales less than 5 meters long rather than larger baleen whales. However, due to climate change, the population of minke whales has plummeted. Based on this, the researchers believe that giant-toothed sharks became extinct due to lack of food.
The statement 'Large whales such as humpback whales and blue whales that lived at the same time as giant-toothed sharks have evolved' most weakens the above conclusion.
