According to current research, which is considered the largest fish that ever lived?
Correct!
According to current research, the megalodon (Otodus megalodon) is probably the largest fish that has ever lived. A 2025 scientific reassessment concluded that it may have reached about 24.3 meters in length and weighed around 94 tons. The answer may seem less obvious at first because many people think of the modern whale shark when they think of very large fish. The whale shark is indeed the largest fish alive today. Megalodon, however, was a shark, and sharks are fish. Based on current size estimates, it was far larger than the whale shark.
According to current research, Megalodon is probably considered the largest known fish in Earth's history because this huge shark may have grown to around 24.3 meters long.
