This course is a phylogenetic survey of the major groups of animals without backbones.  These animals range in size from single cells to giant squids, and they include the vast majority of animals on earth.  Using text readings, assigned articles, and one afternoon per week of field/lab work, students gain an understanding of the classification, ecology, evolutionary relationships, and economic significance of this remarkably diverse collection of organisms.  Students are evaluated on participation, lab notebooks, and performance on weekly quizzes and two tests. 

Level:  Intermediate.  Prerequisites:  Biology I and II or permission of instructor.  Offered every other year.  Class limit: 16.  Lab fee $25.   *ES*
