QUICK FACTSName: “Immortal” seagrass meadowLocation: Shark Bay, Western AustraliaCoordinates: -25.8829486505056, 113.90591540490992Why it is unbelievable: The large meadow fashioned from a single seedling.The crystal-clear waters of Shark Bay are dwelling to the world’s largest plant: a seagrass meadow spanning 77 sq. miles (200 sq. kilometers) and stretching 112 miles (180 kilometers) from finish to finish. The shoots that make up the large meadow all originate from one stem, which researchers estimate is a minimum of 4,500 years outdated.Researchers analyzed the genetic make-up of the seagrass at Shark Bay for the primary time in 2022. They found that the majority the Poseidon’s ribbon weed (Posidonia australis) — which grows in a community of meadows contained in the bay — was genetically equivalent, indicating that the weeds belonged to 1 plant. Not like different varieties of seagrass, which reproduce sexually, this meadow seemed to be regularly cloning itself by means of an underground stem referred to as a rhizome.Associated: 2 crops randomly mated as much as 1 million years in the past to offer rise to one of many world’s hottest drinksOn the sandy seafloor, the self-cloning seagrass meadow varieties clumps of grass that appear to be separate organisms, however underground, the shoots are related to kind “the most important clone in any atmosphere on Earth,” the researchers wrote within the examine.

This implies the Shark Bay seagrass dwarfs the earlier record-holder: The second-largest clone on file is a 9-mile-long (15 km) meadow of Posidonia oceanica seagrass within the western Mediterranean Sea. The meadow at Shark Bay is increasing by means of a course of referred to as “horizontal rhizome extension,” wherein the plant grows stems that reach horizontally beneath the seafloor. These stems then develop vertical stems that develop shoots and leaves, which break by means of the sand to kind seagrass. Primarily based on the scale and age of the meadow, researchers estimate it’s increasing by round 6 to 14 inches (15 to 36 centimeters) per 12 months — which is pretty fast in contrast with different self-cloning seagrass meadows, in response to the examine.The meadow has remained comparatively undisturbed for millennia, which has enabled it to succeed in colossal proportions. The clone might proceed its creeping enlargement for so long as it’s left untouched, making it virtually immortal, Elizabeth Sinclair, an evolutionary biologist on the College of Western Australia, beforehand advised Reside Science.
