A weird extinct whale with a plump body and tiny limbs isn't the heaviest animal to ever live after all, a new study has claimed, bringing with it a whale of a debate.
Last year, a team of researchers unveiled Perucetus colossus, a 39-million-year-old whale from Peru with an estimated body mass of 187,000 to 750,000 pounds (85,000 to 340,000 kilograms) — potentially double that of a blue whale (Balaenoptera musculus).
