Eye of the cyclops: plankton play
Cyclops and its intrepid crew of explorers encounter the denizens of the plankton: micro-crustaceans, insects, rotifers, and protists, organisms with unique adaptations for open water life.
Eye of the cyclops: discovering a forest microcosm
The microexplorers are channeled into the pond outlet, where they tumble into a rapidly flowing stream and discover a world of aquatic insects adapted for life in flowing water.
Branches on the tree of life: the biology of arthropods
Phylum Arthropoda is the most luxuriant branch on the tree of life. This program covers phylum characteristic and three major arthropod classes: Crustaceans (copepods, waterfleas, branchiopods, decapods, and barnacles), Chelicerates (scorpions, pse...

Branches on the tree of life: the biology of plants
Clear graphic animation is used to describe the molecular level mechanisms of photosynthesis. Major plant groups include mosses, liverworts, ferns, horsetails, and the seed plants (gymnosperms and flowering plants). This is a good general introducti...
Branches on the tree of life: the biology of viruses
This program examines the discovery of viruses and their structure, how viruses are studied, how they infect their hosts and how they replicate. Details are provided on the T-4 bacteriophage and retroviruses such as HIV.
Branches on the tree of life: the biology of annelids
Worms with segmented bodies make up the Phylum Annelida. This program explores the three classes of annelids: Class Polychaeta (feeding, locomotion, and larval stages), Class Oligochaeta (lifestyles, feeding adaptations, and anatomy of freshwater o...
Branches on the tree of life: the biology of flatworms
The Branches On the Tree of Life series of core curriculum programs explores the "deep branches" on the tree of life to reveal a modern view of the classification and phylogeny of each group studied in the biology curricula. The narrated programs f...
