We knew Giant Squids existed for years before anyone ever saw a live one (and lived to talk about it) because they leave physical evidence. Aside from bodies that wash up on shore, they leave distinctive wounds on the bodies of whales that dive to the depths where they live. Their beaks, the only hard part of their body, are sometimes found in the stomachs of those whales.
Sharks constantly lose and regrow teeth, and we know megalodon had big ones, yet we don’t find any teeth younger than like three and a half million years old. We don’t see whales with bite marks and scars that would match those of a megalodon. In fact, the fact that we see large whales at all may be more evidence that megalodon is indeed extinct. While megalodon lived whales didn’t get much bigger than today’s killer whales. It is thought that megalodon may have created evolutionary pressure on the size of whales, forcing them to stay small and nimble. If this is the case then large baleen whales, including the blue whale, couldn’t exist unless megalodon is extinct.
