The video is a comparison of the largest creatures on Earth, with a tournament-style competition between prehistoric animals and modern animals. The prehistoric animals win the first four rounds, with the Argentinosaurus, Spinosaurus, and a giant sea scorpion being larger than their modern counterparts. However, the blue whale is revealed to be the largest animal on Earth, with some individuals reaching the size of a nine-story building.
The video then discusses the possibility of giant creatures existing in the ocean, citing the example of the giant squid and the legend of the Kraken. It also explains why giant creatures are more likely to exist in the ocean than on land, due to the buoyancy of water and the fact that marine animals don't have to support their own weight.
The video concludes by discussing the limitations of giant creatures on land, including the strength of their skeletons and the heat generated by their bodies. It also mentions the possibility of insects growing to enormous sizes, but notes that this is unlikely due to the dangers and limitations of their environment.
Finally, the video mentions the largest living organism on Earth, a tree called Hyperion that stands at 115.5 meters tall.
