What is the largest animal that has ever lived?
It is kinda hard to answer. Right now the largest LIVING animal is the blue whale, which weigh from about 150 to 200 tons and can be up to about 80 feet long (few cases around 100 feet). However, there were massive species of Sauropods that would have come close. The problem is they are extinct and no one ever saw them alive to know exacts. Of course with skeletal remains we can get a height and length, but weight can be tricky. Currently the largest classified species of Sauropod was the Argentinosaurus. It ranged about 98-120 feet long. The weight however is a guess and that tends to rest right around 100-120 tons. Thus clearly the whale has more weight but the Argentinosaurus was longer. There are also paleontologists who have said to have found species larger than the Argentinosaurus, but they have yet to be classified (takes a few years). So again, yes and no. Blue whale wins the weight prize but it does not win the length prize… HOWEVER do keep in mind that dino weights are a g
