The Sex Life of the Polyp
Dr. Benchley is attending to the Ladies Club when it come to the reproductive practices of the polyp, a tiny aquatic organism. Although he is unable to show his live specimens, he has actually prepared a series of photos of his subjects. He explains that the subject is made much more challenging by the reality that polyps are able to change their sex every now and then. Then he provides some of the pictures of his specimens and the experiments that he has actually done with them. (IMDb).
