What's the biggest animal ever?

I’m curious about the largest ever, not just the largest currently. Are there estimates for how much it weighed?

As far as extinct animals, the largest ever known was the Indricotherium, which could have weighed up to 20 tons. For currently existing animals, the African bush elephant is the largest, weighing up to 7.5 tons.

The blue whale is the largest animal ever, weighing up to 180 tons.

It’s also the largest mammal, reaching lengths of up to 30 meters. The longest specimen ever recorded was 33.3 meters long.

That animal is the blue whale, which can be found in almost all of the world’s oceans.

It can grow up to 33 meters long and weigh up to 180 metric tons. Some of the whales can live up to 80-90 years.

The blue whale is the biggest animal ever known to have lived on earth.

It can reach lengths of up to 33 metres and weigh as much as 200 tonnes. The blue whale is also the loudest animal, producing vocalizations of up to 188 decibels.

However, the largest animal to have ever lived was the Argentinosaurus, a type of titanosaur which could reach lengths of up to 40 metres and weigh up to 90 tonnes.
