The heaviest blue whale on record is weighed

Assembled from 42 blocks · 1 evidence · 48 related

1. Story
2. A female blue whale taken in the Southern Ocean is weighed at 190 tonnes - the heaviest individual animal ever recorded. It is a different animal from the 33.58 m length record; no single individual holds both. Both records exist only because industrial whaling put the largest animals on Earth onto a factory deck where they could be measured.

41. Evidence
42. 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.
