"Green Patches" is a science fiction short story by Isaac Asimov. It was first published in the November 1950 issue of Galaxy Science Fiction under as "Misbegotten Missionary" and reprinted under its present title in the 1969 collection Nightfall and Other Stories. A research spaceship from Earth lands on Saybrook's Planet to investigate a report by an earlier colony ship. The colony ship's captain, Saybrook, had reported that the planet's abundant plant and animal life was all part of a single organism with a unified consciousness. That organism was able to induce pregnancy in all the colony ship's female animals, and all the offspring born had green patches of fur instead of eyes, a sign that they were part of the planetary organism. When Saybrook had the women in his crew examined and confirmed that they were all pregnant, he sent a sub-ether report back to Earth and then destroyed his ship.
