Paramecium, Hydra, Planaria, Daphnia

Running Time:31 minutes (approx.)
Closed Captioned:Yes
Audio Described:Yes

The classics acquaint students with four organisms often studied in biology. This program introduces students to four organisms we call the Biology Classics, which are featured in most biology textbooks. Studying these “classics” broadens our concept of what it means to be alive.
Structure, behavior, feeding, reproduction, and ecology are observed in each organism, allowing students to compare them. Detailed study guides that can be printed for student use are provided.

Additional information


Observations show how Paramecium moves, feeds, digests, assimilates nutrients, achieves water balance, deploys defensive weapons, reproduces, and engages in the sexual exchange of genetic material. The narrated observations utilize state-of-the-art microscopy-techniques to present a compelling new picture of Paramecium’s life.


Observations of Hydra show feeding behavior, detailed microscopy of stinging cells used in capturing prey, two digestive processes (cellular and extracellular), locomotion, reproduction by budding, development sex organs, and symbiotic guests, both external and internal.


The cross-eyed flatworm, Planaria, is both scavenger and predator depending upon opportunity. Observations show food-seeking behavior, the flatworm’s feeding method, locomotion (produced by a carpet of cilia), internal anatomy, and reproduction through the remarkable process of regeneration.


Daphnia is a classic study in arthropod behavior and anatomy. In living subjects we examine: eye, brain, jaws, intenstine, swimming legs with gills, its beating heart, and two kinds of eggs: those that hatch directly into female daphnia, and resistant eggs that carry the species through periods of freezing and drying.

Customer Reviews:

The four microscopic organisms profiled here are “classics,” according to the accompanying material, not just because of their prominence in biology textbooks, but “because studying them broadens our concept of what it means to be alive.” The Biology Classics: Paramecium, Hydra, Planaria & Daphnia is divided into four parts, each running about 7-8 minutes with individual chapters offering an in-depth look at each organism’s structure, feeding and digestion, reproductive behaviors, and similar life forms in its particular phylum. The microphotography is excellent (it’s great to see a flatworm suddenly take on a bit of drama and flair because of good filming and editing), but it’s the conversational and engaging narration that really sets this program apart from the usual dry microbiology films (here the term “quiescent” is explained by saying that planaria get snoozy). Boasting a solid curriculum, this is highly recommended. Aud: J,H. (E. Gieschen) 3 1/2 of 4 Stars Video Librarian November/December 2006

The Biology Classics: Paramecium, Hydra, Planaria, and Daphnia is a 31 minute program available in DVD, VHS and digital formats. The content and narration are probably most appropriate for middle school/junior high and older science students but could be used on a limited basis with younger students as well. This program is an exceptional instructional tool and is a must have for all life science classrooms. As the title implies, it deals with four organisms likely to be found universally in all science texts. The photography stunningly captures each of the four organisms carrying on the life processes that are common to all living things. Content is clearly presented so students will better understand what it means to be alive and that the life teeming out of view to the eye is similar in many respects to humans. The DVD's main menu deals with each of the four organisms separately. When one of the organisms is selected there is the opportunity to view that section of the program in it's entirety or by subtopic such as digestion/feeding or reporduction. This should allow the teacher maximum flexibility with the media by being able to start and stop the program as needed to facilitate classroom activites. Additionally, each segment includes a series of still microphotographs that can be used individually. The program is interspersed throughout with simple suggestions for finding and rearing Paramecium, Hydra, Planaria, and Daphnia. Teacher's guides and support materials are available on the BioMEDIA website. "Exemplary" Bill Dutton National Association of Media & Technology Centers (NAMTC) August 2006.
