a 6 week old fetus that was the result of the removal of an ectopic pregnancy; the tube was removed and this is what was in the tube. There are a series of pics from that same situation, and my understanding in reading the article that accompanied it, was that the doctor who did the surgery was amazed at the development and ability of the baby. I remember something about him saying the baby was very active, swimming laps in the sac even after the removal of the sac from the tube.
