Frequently asked
What is the heaviest animal ever?
The blue whale, at up to about 190 tonnes. It is heavier than any dinosaur we have good evidence for, because water carries the weight that legs otherwise would.
Why is this on a logarithmic scale?
Because a cat and a blue whale differ by a factor of 33 000. On a linear scale every animal but the whale would be an invisible line.
