Can anyone identify this creepy wee beastie. It appeared on my table this morning. No idea where it came from or what it is. I’m in Australia so some kind of antipodean monstrosity? I have a video of it moving but don’t know if I can attach it. It has a wormy head that pokes out and pulls its body along. The head disappears ( like a tortoise’s head does) when it is not moving. Any ideas?
