Can a detached euphyllia polyp from a dying euphyllia still sting?

As the title says, I have a dying euphyllia head whose polyps are falling off and being carried around the water column. My Duncan seemed to have caught one of these polyps, but did not eat it. The Duncan’s tentacles that touched the polyp has shrunk a bit. Can the detached euphyllia polyp still sting?

Yes it can. As long as the polyp doesn't stick to another coral, all should be okay. Keep an eye out for infection though.
