The Heaviest Animals

The world's heaviest animals – presented in one well-arranged chart! Plus additional exciting infos!

If we had simply made up a top ten list of the heaviest animals, neither the polar bear nor the leatherback sea turtle would appear in it. All ten slots would be occupied by whales exclusively. That's true!

But why? The blue whale is not the only heavy whale. Right whales such as the North Pacific right whale, the southern right whale, the North Atlantic right whale, and the Greenland right whale (to mention just a few) are much heavier than all the other animals, too. They weigh between 50 and 100 tons. That's why we've picked records from the most diverse animal orders and genera.

Gosh, They Are So Big!

In movies even big animals often look rather sweet and not as chubby and heavy as they really are. A polar bear and the leatherback sea turtle alone are as heavy as a small car. Have you ever tried to lift a car with your hands? Then you know what this means.

190 Tons? How Much is This?

A blue whale can weigh up to 190 tons. For comparison: A blue whale weighs as much as 10 city busses, 95 helicopters or 2,000 human beings. This is still hard to imagine, isn’t it?

How Do You Measure the Weight of a Whale?

Personal scales (those in the bathroom) mostly can only measure weights of up to 308.6 lb (140 kg). So how do you measure the weight of giraffe or an elephant? For this purpose the animals are led onto a weighbridge. These devices are designed for weights of up to 60 tons.

So far so good, but how does it work with a blue whale? It is much heavier than 60 tons. And how can you get the animal out of the water to put it on the weighbridge? The exact weight of living whales can usually only be estimated. Yet you can measure the weight of stranded (dead) animals by means of a crane scale.

The Largest Dinosaur

Dinosaurs were the largest and heaviest terrestrial animals that ever lived. But even they cannot compete with the blue whale.

With up to 100 tons, the Argentinosaurus is considered to be the heaviest dino. Scientists have been arguing about the exact weight for ages, but they can only revert to the dino’s bones to get a rough idea.
