The seagrass that covers about 200 sq km (77 sq miles), spread from a single seed over at least 4,500 years, was discovered at Shark Bay in Western Australia.
The largest known plant on Earth was discovered in the shallow, sun-drenched waters of the World Heritage Area of Shark Bay in Western Australia. Scientifically known as Posidonia australis, the sea grass ribbon weed meadows was discovered by the researchers from University of Western Australia and Flinders University.
Scientists confirmed that the meadow was a single organism by sampling and comparing the DNA of seagrass shoots across the bed.
Pando, an aspen clone that originates from a single seed and spreads by sending up new shoots from the expanding root system was believed to be the largest, most dense organism ever found at nearly 13 million pounds covering about 106 acres, livinig in Fishlake National Forest in Utah. in US.
The seagrass supports dugongs, dolphins and fish as well as capturing tonnes of carbon dioxide. The plant has astonishing capabilities to withstand extreme climatic conditions. The scientists estimated it to be around 4500 years old by rate at which it grows per year which is about 35 centimeters.
