Bamfield Field Trip:

  • Want to see stunning marine invertebrates in their natural habitats? Consider going on the optional Reading-Week field trip to the Bamfield Marine Station.
Lecture & Laboratory Study Materials:

  • View the entire classification of animals (to subclass) as in the course text or check out the classification of particular groups at GenBank.

  • ProtoDeutero.jpg, 13K     Browse the Tree of Life of animal phyla as followed in Zool 250 and review key characters defining major branches.

  • Having trouble remembering some of the material you saw in lab? Maybe the study images of prepared slides and dissections will help.

  • Still mulling over key concepts or processes discussed in lecture? Some entertaining and informative animations are available for review or self test.

  • Self-testing exams may help you prepare for lecture and laboratory exams.

  • Ever wonder about the meaning of scientific names of animals or body parts? Search the table of Greek & Latin roots for clues.
