A message from social media about this sighting: "Hi can you describe its features please that set it apart as invasive exotic? I thought Naturemapr was mostly for spotting our native species. Seems like a lot of slugs around this year!"

Hi Matthew,
If you click on the species link there is often a bit of information. The info for this slug reads: "Hailing from Europe this invader has become a highly invasive species in cooler parts of Australia, invading native vegetation along creek lines and temperate rainforests. There is a cream/yellow form and a grey colour form. It is called a hedgehog slug because tiny segments on its body stick out reminiscent of hedgehog quills when the slug retracts into a ball. "
