The document contains a table with images. The images are examples of each Phylum: Porifera, Cnidaria, Platyhelminthes, Annelida, Mollusca, Arthropoda, Nematoda, Echinodermata, and Chordata.

First, use the table in your textbook (page 428) to determine which Phylum each organism falls into (you will find a description of chordata on page 450). List the specific traits that distinguish each Phylum . (Please do not just copy the list from the table. Read through the text to pull out detailed characteristics.)

Next, download the document, Table II (See attached file), and use the Dichotomous Key to help determine the taxonomic category in which each specific organism belongs. For help on how to use the Dichotomous Key, download the document, U5IP_How_To_Dichotomous_Key
