Branches on the tree of life: the biology of echinoderms
Echinoderms are one branch of the deuterostome line of animal evolution, the branch to which Chordates also belong. Modules cover phylum characteristics and key biological details for five classes: sea stars; brittle stars and basket stars; sea urc...
Branches on the tree of life: the biology of fungi
Branches on the Tree of Life: Fungi explores the structure, life cycles, ecology, classification, and evolutionary relationships of four major lines of fungi: Chytrids, Zygomycetes (various molds), Ascomycetes (yeasts, cup fungi, and most lichens), ...
Branches on the tree of life: the biology of sponges
Imagine an animal with no mouth, no digestive system, no excretory or circulatory organs, no brain nor nervous system, and no movement as an adult. In spite of their simple nature, sponges are actually one of the most fascinating animal phyla, when...

Eye of the cyclops: predators of the shallows
While engrossed in observing the food capturing and feeding methods used by Planaria, a flatworm, the tentacles of Hydra trap the Cyclops crew where they receive a hands-on lesson in the process of digestion.
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.
Branches on the tree of life: the biology of algae
The term algae is a catchall for several evolutionary lines of photosynthetic organisms: dinoflagellates: red algae (plastids with chlorophyll A); diatoms, yellow-brown algae and brown algae (chlorophylls A and C); and green algae (chlorophylls A an...
Branches on the tree of life: the biology of rotifers and nematodes
The diversity of rotifers is stunning, and this program shows many different species. Planktonic rotifers have special adaptations for open water life. Nematodes (round-worms) include a number of important human parasites, seldom seen but easily f...
