Pando is the largest tree by weight and landmass and the largest known aspen clone. Pando was identified as a single living organism because each of its stems possesses identical genetic markers. [2] The massive interconnected root system coordinates energy production, defense and regeneration across the tree's landmass. [3]
The largest such colony is Pando, in the Fishlake National Forest in Utah. A form of flowering plant that far exceeds Pando as the largest organism on Earth in area and potentially also mass, is the giant marine plant, Posidonia australis, living in Shark Bay, Australia.
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.
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 ...
Armillaria mellea Armillaria hinnulea. The basidiocarp (reproductive structure) of the fungus is a mushroom that grows on wood, typically in small dense clumps or tufts. Their caps (mushroom tops) are typically yellow-brown, somewhat sticky to touch when moist, and, depending on age, may range in shape from conical to convex to depressed in the center.
A clonal colony can survive for much longer than an individual tree. A colony of 48,000 quaking aspen trees (nicknamed Pando), covering 106 acres (43 ha) in the Fishlake National Forest of Utah, is considered one of the oldest and largest organisms in the world. Recent estimates set the colony's age at several thousand (up to 14,000) years ...
The beetles are the largest order of organisms on earth, with about 400,000 species so far identified. The most massive species are the Goliathus , Megasoma and Titanus beetles already mentioned. Another fairly large species is the Hercules beetle ( Dynastes hercules ) of the neotropic rainforest with a maximum overall length of at least 19 cm ...
More than 99 percent of all species, amounting to over five billion species, [7] that ever lived on Earth are estimated to be extinct. [8] [9] Estimates on the number of Earth's current species range from 10 million to 14 million, [10] of which about 1.2 million have been documented and over 86 percent have not yet been described.
