What's the common name?

I think this is a Starites quadriceps. That's what google lens says anyway, and it looks about right to me. But I can't find the common name and I knew it but can't remember. Poor thing was dead on the patio today after either the deep freeze or my dog trying her best to be bestie with it - not sure, but think it was the cold. Lens also thinks it might be S. Terricola? I think the 1st though. Can anyone confirm and give the common name and even some fun facts. Can't find anything but these two names.
