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 viewed in developmental, ecological, and evolutionary terms.

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 and B). This program explores the diversity, structure, ecological roles and modern classification of these vital primary producers.
