Bassian ecoregion

The Bassian ecoregion is a biogeographic region of Australia's coastal and continental shelf waters.

This ecoregion, designated in the Marine Ecoregions of the World system by the World Wildlife Fund (WWF), includes both the Bass Strait Shelf and Tasmanian Shelf provincial level bioregions from the Integrated Marine and Coastal Regionalisation of Australia (IMCRA) system.

On the Victorian Coast it extends from east of Cape Otway to Waratah Bay.

It excludes King Island and the western end of the Bass Strait, which belongs to the adjacent Western Bassian ecoregion, and to the east it excludes the Furneaux Group of islands and the eastern end of the Bass Strait, which belong to the adjacent Cape Howe ecoregion.

[3] The province is characterised by cold temperate species which also dwell in the adjacent transitions.
