The longest blue whale on record is a female measured at a South Georgia whaling station at 33.58 m; the heaviest is a separate female taken in the Southern Ocean on 20 March 1947 at 190 tonnes. V55 verification basis: retrieved in search summary attributed to Guinness World Records; the entries were not fetched, and the sources retrieved disagree on whether the length record dates from 1909 or c.1912 - the disagreement is preserved rather than resolved.

A evidence is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
