It's not Kraken sized, exactly, but it could try to eat a London bus. Researchers have retrieved an example of a colossal squid, yclept Mesonychoteuthis hamiltoni .
Then again, half a millennium or more ago, ships were much smaller. Columbus's ships averaged less than 3 times the length of the modern London bus. And this was considered to be an "immature" specimen of colossal squid. So… perhaps this is a descendant of the famed kraken after all!
