[48] [49] Apart from its extreme age, it is also thought to be the world's largest organism by area, at 2,384 acres (965 hectares). A huge colony of the sea grass Posidonia australis in the Australian coast over Shark Bay, estimated to be over 4,500 years old and also the biggest known plant. [50] [51]

[ 15 ] [ 60 ] [ 61 ] The extinct whale species Perucetus colossus was shorter than the blue whale, at 17.0–20.1 meters (55.8–65.9 ft) but it is estimated to have rivaled or ...
If this colony is considered a single organism, it is one of the largest known organisms in the world by area, only knowingly rivalled by a colony of Posidonia australis on the Australian seabed that measures 200 square kilometres (77 sq mi; 49,000 acres), and rivals the aspen grove "Pando" as the known organism with the highest living biomass.
Scientists have discovered one of the largest known sea creatures – a coral the size of two basketball courts – off the Solomon Islands in the South Pacific.. The coral is believed to be ...
The Hazelwood Tree (not listed above) had a volume of 1,025.86 m 3 (36,228 cu ft) before losing half its trunk in a lightning storm in 2002, if it were still at full size it would currently be the 17th largest giant sequoia on earth. The largest giant sequoia killed at the hands of man was the Discovery Tree at Calaveras Grove, which was cut ...
