Posidonia Australis – Biggest Plant in World | Length 180 km

Posidonia Australis : The world’s largest living plant has recently bee discovered in the shallow waters off the coast of western Australia. This plant spans an area of about 20000 hectares.

About the News

The largest living plant has been identified by researchers from Flinders University in the South Australia and the University of Western Australia . According to their report, it a seagrass stretching 180km ( 200 km2 ) in Western Australia’s Shark Bay. The researchers has estimated that it is at least four thousand fiver hundred years old.

Key Points

  • This is roughly three times the size of Manhattan.
  • This plant has double the number of chromosomes than other similar plants .
  • This plant have managed to survive in the volatile atmosphere of the shallow shark bay
  • It is estimated that this plant is 4500 years old.
  • This plant is stretched across 180 km – which is the about the approximately distance between Mumbai and Pune ( ~150 km)
  • This study has been done by the researchers of Flinders University and the University of Western Australia.
  • The findings of the researchers have been published in the journal Proceedings of the Royal Society B.
  • This plants comes in the category – ribbon weed.
  • The team of researchers have setup further test to better understand how the ancient plant survives in such extreme conditions.

About the Plant

The plant spans a total area of nearly 20000 hectares ( 49,000 acres). This plant has double the number of chromosome than any other similar plants. Generally such plants have 20 chromosomes, but this plant have 40 chromosomes. This plant usually grow to around 35cm per year. According to the researchers ,this plant does not spread its seeds. This plant has survived in such conditions because is a polyploid. A polypoid have 100 percent genome from the parents ( not half -half from each parent). These plant can survive in extreme conditions and continue to grow if left undisturbed.

This plant spreads out like meadow as a result it become a habitat place for marine species like turtles, dolphins, fish ,etc. Studies have resulted that such plant can live upto 1,00,000 years.

According to Dr. Elizabeth Sinclair “It appears to be really resilient, experiencing a wide range of temperatures and salinities plus extreme high light conditions, which together would typically be highly stressful for most plants”
