Seagrasses of Western Australia

I just browsed through a scientific article about seagrasses in south-west Australia this arvo. I find these points quite amazing:
  • Out of the 50 seagrass species found globally, 19 can be found in south-west Australia.
  • These 19 species represent 8 of the 13 seagrass genera.
And I read this on the Net:
  • Shark Bay of Western Australia, which is a world heritage site over 800 km north of Perth, has the largest seagrass meadows in the world. Seagrasses cover over 4 000 km² of the bay!
  • And Wikipedia says this: 'Shark Bay has the largest number of seagrass species ever recorded in one place; 12 species have been found, with up to 9 occurring together in some places.'
I wonder if it is an exaggeration to call Western Australia a paradise for seagrass researches.

Strapweed (Posidonia sp.) and Syringodium isoetifolium (still can't find its common name) in Bickley Bay, Rottnest Island.


  • The paper mentioned above was written by T.J.B. Carruthers, W.C. Dennison, G.A. Kendrick, M. Waycott, D.I. Walker and M.L. Cambridge.
  • The title of the paper is 'Seagrasses of south-west Australia: A conceptual synthesis of the world's most diverse and extensive seagrass meadows'. It was published in the Journal of Experimental Marine Biology and Ecology in 2007.
