Largest Organism in The World

Ever wonder what the largest organism in the entire world is? Is there really only one organism spectacular enough to hold such a title all by itself?

What is the largest organism on Earth you ask? The largest organism in the world can depend on how you decide measure it. It could be the organism with the largest height, length, mass or volume, which could produce several title takers.

Aspen trees (populus tremuloides) grow together and can form long strings of genetically identical trees, which are connected by one distinct root system. They do not in every case remain a single unit, however the Pando Aspen trees, is often considered the largest organism on Earth. Pando is a grove situated in Utah of Aspen trees, which stretches 0.43 km2 or 106 acres and weighs approximately 6,000 tons, which makes it the largest organism by mass.

If the largest organism on Earth, however, were measured by area, then the title would alternatively have to go to the Honey Mushrooms (armillaria ostoyae), a large fungus specie. The Malheur National Forest in Oregon is home to Honey Mushrooms which span 8.9 km2 or 2,200 acres. There are some disputes, however, on whether it is an individual organism, although several tests have shown that the Mushrooms do have genetically identical makeup.

If volume and weight were the determining factor of the largest organism then the title would again be given elsewhere, to a Giant Sequoia tree. The General Sherman tree is considered the Earth’s largest undisputed single organism in terms of volume. The Giant Sequoia has a volume of 1, 487 m3 or 52,500 cu ft and it is 83.8 m or 275 ft tall with a trunk that is considered to weigh more than 1,800 tons.

Organisms, along with the Earth, are constantly evolving, and what we consider some of the largest organisms of today could someday be outdone by other ever more spectacular organisms.

    Apparently there is no proof at all for the age, which is “believed” by a handful of people.

    In Prairie Creek, I saw a stand or row of curly redwood that are good evidence that comparable or larger redwood clonal stands may exist. I recall about 6 to 8 big redwoods in the row, likely all connected root to root. Others off to the side may be connected too. That was not related to our tree measuring task, so we just moved on. The clonal stand limits are a tangent we don’t get involved with. Too much forest, too little time. And not much profit from the hunt anyway.
