COELENTERATA, REEL I AND CTENOPHORA
Sign in to track this film in your collection or want list.
This is a revision of two films, now combined to illustrate some common representatives of the coelenterates. The common hydranth of Tubularia is seen in considerable detail as a piece of the portion of the individual is magnified to fill the screen. Metridium demonstrates the activity of the tentacles and mouth during feeding, and the contraction of longitudinal muscles upon stimulation. The structure of the ctenophore Beroe is clearly brought out by suitable lighting.
