En enkelt ålegræs plante dækker 180km
Store, flerårige ålegræsenge af Poseidon’s ribbon weed og wire weed (Amphibolis antarctica) dominerer en stor del af det marine økosystem i UNESCO’s verdensarvsområde Shark Bay i Australien.
For to år siden opdagede forskere, imidlertid at noget af havgræsset var en klon af Poseidon’s ribbon weed (Posidonia australis), som havde 40 kromosomer i stedet for de typiske 20. De mener, at halvdelen af kromosomerne kommer fra ålegræsset og halvdelen fra en ukendt art.

Along the continent’s southern coast is an undersea world far removed from the tropics.
