The Sex Life of the Polyp
Dr. Benchley is addressing the Ladies Club when it come to the reproductive routines of the polyp, a tiny water microorganism. Although he is not able to present his live samplings, he has prepared a series of images of his subjects. He clarifies that the subject is made a lot more challenging by the truth that polyps have the ability to change their sex periodically. Then he offers a few of the pictures of his specimens and the experiments that he has actually made with them. (IMDb).
