In my previous posts I have written about some of our inspiring encounters with the magnificent wildlife of Shark Bay. The Malgana people used to call this land ‘Two Bays’ or Gutharraguda – referring to the shallow waters of Hamelin Pool between Peron Peninsula and the mainland in the North and Henri Freycinet Harbour between Peron Peninsula and Dirk Hartog Island in the South. The old map of French navigator Henri Freycinet shows this piece of remarkable Australian shoreline best.
Shark Bay is a unique area with vast beds of seagrass, forming massive meadows in the shallow and warm waters. Seagrasses provide both food and shelter for the stunning array of marine life, but also bind sediments moved in through tides and currants. Accumulated sediments have formed the numerous banks, sills and channels that have turned some of the bay’s waters hyper saline – the area around Hamelin Pool is twice as salty as the open ocean! Although hostile to many animals, the extreme salinity of Hamelin Pool forms the perfect habitat for Stromatolites – single celled cyanobacteria that were the only evidence of life on earth until around 500,000,000 years ago. The history, wildlife and beauty of this place is simply unique, and we are therefore sure we will return soon to the land of where the red desert meets the blue ocean.
