Further Investigations: Structure and Function

  1. The first animals to actively hunt other living organism were invertebrates. What are some physical features that might aid a predatory invertebrate in hunting its prey? Consider issues of locomotion, sensory systems, and body size. Watch the documentary film series Shape of Life as a resource.
  2. Many invertebrate phyla evolved new modes of locomotion or ways of moving about on their own. Prepare a table listing the different ways invertebrates move, both in water and on land.
  3. Invertebrates were the first organisms to conquer the skies with flight under their own power (as compared to plant seeds or fungal spores blown by the wind). Which invertebrate phyla have flying taxa? Compare their methods for achieving flight.
