What is the largest creature ever to live?
The blue whale is the largest creature ever to live on Earth. This marine mammal can reach lengths of up to 100 feet and weigh as much as 180 tons. Blue whales are not only impressive in size but also in their swimming capabilities and deep dives. They primarily feed on krill and are found in various oceans around the world.
What is the fattest animal to exist?
The blue whale is also considered the fattest animal to exist, given its sheer mass and volume. Weighing up to 180 tons, their bodies are supported by massive amounts of blubber, which insulates and provides energy reserves. This adaptation is crucial for their survival in the cold, deep waters they inhabit. Blue whales store energy during feeding times to sustain themselves during leaner periods.
