Unique marine life of Bathurst Channel, Port Davey, southwest Tasmania, Australia

The marine environment in the Bathurst Channel in the remote southwest of Tasmania is truly unique. The Bathurst Channel is a sunken river valley joining Bathurst Harbour to the sea in Port Davey. Dark red tannin-stained freshwater from the surrounding buttongrass plains forms a surface layer over the clear seawater underneath, reducing sunlight to almost zero. The conditions in only 4m depth are like the deepsea - very dark with little temperature variation, and the life present are all deepsea animals - there are no plants. Amazing large seapens, fields of seawhips, masses of undescribed species of soft corals, reefs made of bryozoans, usually found in 50-200m depth, are all found here in depths of less than 15m. This delicate and unique area has been protected in a marine park. Filmed by Michael Baron, photography by Karen Gowlett-Holmes.
