Ghost Crabs are found in tropical waters, from the Kimberley in Western Australia, Northern Territory, Queensland to Sydney, New South Wales. This project forms the basis for a Masters by Research study by Ms Cailtin Rae, who will quantify ghost crab abundances along the beaches and dunes of the mid-west region and determine the influence of beach-cast wrack on their abundances and feeding patterns, as well as their role in moving marine material into the dunes and provide food and nutrients to dune systems.
