They are de-headed
My bull headed sister did that to about 20 lbs of crawfish that was left over the last time I boiled. I was in the den watching sports on the tube while the last eaters were re-stuffing themselves for the 4th or 5th time. They knew I wanted to keep a bunch of the left-overs to bring home, and she de-headed every last one of them. It pissed me off!
On the re-heating quetion, I normally eat them cold, but they do surprisingly well in the microwave.
