AN EXTENSIVE stretch of coastline remains closed off Mandurah as a whale carcass attracts predators.
It was reported that the carcass had washed ashore near Admiralty Crescent in Halls Head about 9am this morning.
Authorities believe the carcass will act as an attractant leading to sharks coming close to shore.
Surfers and swimmers are asked to take extra precautions while in the water and to obey beach closure signs.
Beaches remain closed between Falcon Bay and Doddies Beach.

The land manager is assessing the situation and considering removing the carcass.
The carcass, which has been identified as a humpback whale, is drawing a huge crowd to the beach taking photos.
Authorities confirmed this is the same carcass spotted off James Service Reef five days ago.
