The Sex Life of the Polyp
Dr. Benchley is dealing with the Ladies Club when it come to the reproductive practices of the polyp, a tiny water organism. Although he is unable to display his live specimens, he has actually prepared a series of photos of his subjects. He discusses that the topic is made much more challenging by the reality that polyps have the ability to alter their sex from time to time. Then he presents a few of the pictures of his samplings as well as the experiments that he has finished with them. (IMDb).
