What's the biggest single living organism on Earth?

Question

Single living organism lets out any fungi or Reef makers.

Think more along the lines of Flora, not Fauna.

Answer 1

The largest organism found on earth can be measured using a variety of methods. It could be defined as the largest by volume, mass, height, or length. Some creatures group together to form a superorganism, though this cannot truly be classed as one large organism. (The Great Barrier Reef, the world's largest coral reef (stretching 2,000 km) has been shown to be a collection of many organisms and is the largest known superorganism, though Gaia theory would consider the whole of the biosphere as a sort of superorganism.)

The Aspen tree (Populus tremuloides) forms large stands of genetically identical trees (technically, stems) connected by a single underground root system. These trees form through root sprouts coming off an original parent tree, though the root system may not remain a single unit in all specimens. The largest known fully-connected Aspen is a grove in Utah nicknamed Pando, and some experts call it the largest[1] organism in the world, by mass or volume.[2] It covers 43 hectares (.43 km²) and is estimated to weigh 6,600 tons. [3]

A giant fungus of the species Armillaria ostoyae in the Malheur National Forest in Oregon was found to span 8.9 km² (2,200 acres)[1], which would make it the largest organism by area. Whether or not this is an actual individual organism, however, is disputed: some tests have indicated that they have the same genetic makeup [2], but unless its mycelium is fully connected, it is a clonal colony of numerous smaller individuals. Another clonal colony that rivals the Armillaria and the Populus colonies in size is a strand of the giant marine plant, Posidonia oceanica, discovered in the Mediterranean Sea near the Balearic Islands. It is about 8 km (4.3 miles) in length.

Excluding multi-stem trees, the General Sherman tree, an individual Giant Sequoia with a volume of 1487 m³, would hold the title of the world's largest living organism, if measured in volume and mass.[3] This tree stands 83.8 m (274 ft 11 in) tall and the trunk alone is estimated to weigh over 2000 tons. The largest single-stem tree ever measured was the “Lindsey Creek Tree,” a coastal redwood with a minimum trunk volume of over 2500 m³ and a mass of over 3600 tons, which fell over during a storm in 1905.[4]

By volume and weight, the largest known animal ever to have lived is the blue whale, an endangered species whose official record length is 33.58 m (110 ft 2 inches), and weight 210 tons (for a pregnant female). The largest land animals today are male Savannah Elephants, with one known example weighing around 12,272 kg (27,000 lb), though many extinct species, such as many dinosaurs, were much larger.

The largest extinct Predator is the Spynosouras, the largest Extinct herbivore is the Brachiosouras.

Answer 6

The largest undivided cell organisms are the Slime Molds. Most are very small, but the largest can cover an area of about 2 square meters.

The largest "Super-organism" is the Great Barrier Reef, which is made up of multiple living organisms.

Answer 7

Hey i'm here for the first time. I found this question and I find the answers truly valuable. I'm hoping to offer something back to the community and assist others too.

Answer 8

Aspen Trees.

Edit: im sorry i was mistaken they are the oldest living organism i believe. I suppose a Coral Reef may be the biggest organism.

Answer 9

From what I remember in high school, it was a sperm whale, mammal wise. And I'm not sure what you're looking for when you say "organism." The coral reefs, mammals, what exactly?? But just to be safe, Google it. 'Cause I've been out of high school alot of years.

Answer 10

The largest living thing on earth is the blue whale. Their heart is the size of a car. But they only eat extremly small krill.
