  • Cnidarians

    • Video
    A sea anemone with a captured crab, surrounded by other plant life. Caption: Even a large crab can be digested within a few hours.

    Part of the "Branches on the Tree of Life" series. Begins with a series of observations on Hydra, including habitat, structure, feeding, nematocyst discharge, locomotion (by looping), and its sexual and asexual reproductive strategies. Obelia illustrates the two-stage life cycle found in many cnidarians. Examining the biology of jellyfish (class Scyphozoa), sea anemones, and corals (class Anthozoa) rounds out the overview of phylum Cnidaria.

  • Small insect on the tip of a leaf. Caption: Ticks are parasites of birds and mammals.

    Part of the "Branches on the Tree of Life" series. Phylum Arthropoda is the most luxuriant branch on the tree of life. Covers phylum characteristics and three major arthropod classes: Crustaceans (copepods, waterfleas, branchiopods, decapods, and barnacles), Chelicerates (scorpions, pseudoscorpions, spiders, ticks, and mites), and Uniramians (centipedes, millipedes, and insects). Focuses on adaptations, life cycles, and evolutionary relationships in each section.

  • Microscopic view of a transparent tube-shaped organism. Caption: an energy reserve the cell can draw on

    Part of the "Branches on the Tree of Life" series. The term "protist" covers a wide range of microscopic organisms formerly clumped into "Kingdom Protista." New molecular analyses show that the protistan lines of evolution go so far back in time they can be considered as different kingdoms of life. Through photography of living protists, amoebas, flagellates, algae, and the elegant ciliated protists are introduced in ten learning modules.

  • Beach with algae and other objects on it. Caption: Converting bacteria and organic material into protein,

    Part of the "Branches on the Tree of Life" series. Worms with segmented bodies make up the phylum Annelida. Explores the three classes of annelids: Class Polychaeta (feeding, locomotion, and larval stages), Class Oligochaeta (lifestyles, feeding adaptations, and anatomy of freshwater oligochaetes and earthworms), and Class Hirudinea (leeches, crayfish, and worms show adaptations for commensal, parasitic, and scavenger lifestyles). DNA evidence places annelids close to the molluscs on the tree of life.

  • Sea floor with irregularly shaped white objects on it. Caption: composed almost entirely of hexactinellid sponges.

    Part of the "Branches on the Tree of Life" series. 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 interesting animal phyla when viewed in developmental, ecological, and evolutionary terms. Clarifies the structure, function, classification, and ecological roles of sponges through animations and time-lapse microscopy.

  • Crab with red legs and a darker body. Caption: Most of the year, the red crabs live in their burrows inland.

    Christmas Island, discovered December 25, 1643, is just a spec of land in the Indian Ocean. The annual red crab migration at the beginning of the rainy season, however, is so massive it can be seen from the air. It has been named a wonder of the natural world. Follows this terrestrial arthropod from its rainforest burrow, across dangerous landscape to the ocean to mate.

  • Person using a wooden mallet to break open a stone. Caption: About half have something in them.

    How is it that a museum can have over twelve hundred fossils of a particular species in its collection and not even know what it is? For decades, it was thought the Tully Monster, a bizarre animal that lived 307 million years ago, was an invertebrate. However, as host Emily Graslie reveals in this episode, scientists at The Field Museum finally cracked the mystery of the monster. It is actually related to lamprey fish. Part of "The Brain Scoop" series.

  • Example of two kinds of Protista, euglena and protozoa. Caption: Nearly all the organisms placed in the Protista kingdom

    Presents a brief history of what new information caused the classification of living things to evolve from the original two kingdom classification of animals and plants by Linnaeus in the 18th century to the present-day six kingdoms: Animal, Plant, Fungi, Protista, Eubacteria, and Archaebacteria. Discusses three of the six kingdoms: Protista, Eubacteria, and Archaebacteria. Also, presents the hierarchical classification from kingdom to species. Because viruses do not have the capability of an independent cellular life, they are included in neither the kingdom nor domain classifications.

  • Small translucent speckled animal nestled on pebbles. Caption: but the Hawaiian bobtail squid is a master of disguise.

    The Hawaiian bobtail squid and its resident bacterium, Vibrio fischeri, have a powerful and still somewhat mysterious symbiotic relationship. The luminescent bacteria populate a small pouch on the squid’s underside called the light organ, and provide a sort of “Klingon cloaking device.” They produce light at night to offset the squid’s shadow and hide it from predators when it approaches the ocean’s surface to feed. At the University of Wisconsin-Madison, microbiologist Margaret McFall-Ngai studies this unusual relationship. An understanding of these creatures’ rhythms could lead to new ways to treat disease. She is also studying how the squid and bacteria communicate, so they don’t harm each other.

  • Underwater rock with plants on it. Caption: To live in fast water requires special structures

    Part of the "Life in Aquatic Environments" series. Places many of the organisms into an ecological perspective of hydras, planarians, annelids, aquatic insects, rotifers, protists, and all other organisms that provide food for fish and other vertebrates. Observes adaptations for planktonic life in daphnia and other cladocerans, copepods, rotifers, and planktonic algae. Explores bacterial decomposition, recycling of materials, adaptations for bottom life, and ecological relationships in the bottom community. Takes an underwater look at the highly specialized organisms that live in rapids, under rock communities, and in slower waters. Investigates adaptations for life in temporary wetland environments.
