Dr. Benchley is dealing with the Ladies Club on the subject of the reproductive habits of the polyp, a tiny aquatic microorganism. Although he is unable to show his online samplings, he has actually prepared a collection of pictures of his topics. He describes that the topic is made much more complicated by the fact that polyps are able to alter their sex periodically. After that he offers a few of the pictures of his samplings as well as the experiments that he has actually performed with them. (IMDb).
