What is the largest animal to have ever lived?

Answer 1

The largest animal that ever lived, is alive now, and is the Blue Whale, however, there are two Dinosaurs that could perhaps be larger. Amphicoelias Fragillimus, which if existed would have been up to 196 feet long and 122 tons. Also, Bruhathkayosaurus Matleyi, which possibly was 110 feet long and 139 tons. Blue Whales reach 108 feet long and 172 tons. The Blue Whale is the heaviest animal ever, but possibly not the longest.

Answer 2

The blue whale. I know most people will say some kind of dinosaur, but this is not true. I recently saw a chart in Smithsonian that compared the top biggest dinosaur skeletons to a blue whale's. The whale was, by far, the biggest.

__________________________________________________________________

The blue whale is simply NOT the biggest animal to ever live by far. The short answer is, BLUE WHALE is the HEAVIEST animal to ever live. AMPHICOELIAS (sauropod dinosaur) was the LONGEST animal to ever live. SAUROPOSEIDON (sauropod dinosaur) was the TALLEST animal to ever live.

The term "large" could be defined in terms of weight, length, or even height. In addition, when you use the phrase "to ever live on Earth", I think you have to consider at least the low-end estimates provided by paleontologists and researchers who analyzed fossilized remains.

The heaviest blue whale recorded weighed roughly 195 tons. The longest blue whale recorded was 110 feet, but this whale was not weighed. It is likely it weighed close to 200 tons or slightly more. The Bruhathkayosaurus, a prehistoric sauropod (titanosaur), was estimated to be the heaviest dinosaur ever to live, weighing 139-175 tons (scaled back from a previous estimate of 175-220 tons that was declared inaccurate by the original researcher). The blue whale still outweights it, therefore making the BLUE WHALE is the HEAVIEST animal to have ever lived, which should not be surprising given that it lives in the ocean. There is always the possibility that prehistoric whales or land-dwellers weighed more, but no evidence of that has yet been found.

The Amphicoelias was also a sauropod dinosaur, a fossil of which was studied in the 1870s. The fossil has since gone missing (not sure what that means). However, studies were done before it was lost, and field notes suggest the animal could grow to between 130-200 feet in length. Even this low-end estimate is longer than that of the longest blue whale we have ever recorded. Therefore, in my view it is safe to assume that AMPHICOELIAS was indeed the LONGEST known animal to have ever lived (130-200 ft). If other, longer whales or dinosaurs existed, no evidence of them has been found.

Sauroposeidon, another sauropod dinosaur, stood at an amazing 56 feet (6 stories) with its neck extended, making it the tallest known animal to ever walk the earth. By comparison, the Brachiosaurus stood 30 feet high and the tallest modern giraffe stood 20 feet high. Therefore, SAUROPOSEIDON was the TALLEST known animal to have ever lived. If anything taller existed, we do not know about it.

Again, you can't expect these estimates to be 100% accurate when you are talking about animals that lived hundreds of millions of year ago. Yet these studies involved scaling the bones of better-known species in the sauropod family, assuming their relative proportions were similar. The low-end estimates are probably correct, and at least have not been seriously called into question.

Answer 3

The largest living animal is the blue whale
The Blue Whale

Answer 4

Pre-historic whales and other marine life. Blue whale is the largest still living animal. Paleontologist have found bones from an animal that they have estimated to be 44m (144ft).

Answer 5

The blue whale is larger than any dinosaur. It is the largest animal to exist or to have ever existed.Definitely the blue whale.

Answer 6
