Textbook Question
Chapter 30, Problem 12PIAT
Sperling and Knoll’s approach was to compare the number of predatory polychaete worms (pronounced pol-ee-KEET, phylum Annelida) living today in different low-oxygen environments. They chose polychaetes as a model system because these worms have diverse feeding strategies and live in diverse marine environments, yet all have the same basic body plan. Using Figure 30.2 as your guide, describe the body plan of a polychaete worm.
