A photo of a huge spider hanging from a roof has sparked concern, with some joking that the homeowner should move out. A concerned man in Baldivis, 45km south of Perth, shared the scary image on a local Facebook community group and asked for help identifying the mammoth arachnid. It shows the spider sitting in a web with its long pointed legs curled up under a bulky dark abdomen, as if it is ready to pounce. The original poster described it as 'one of the biggest I've seen'.
