    Animals are placed in taxonomic classifications based on differences and similarities of their traits. If you know what critical traits to look for, it is possible to separate any animal into a taxonomic category.

    The common categories are Domain, Kingdom, Phylum, Class, Order, Family, Genus and Species (Specific Epithet.)

    Example: Human Classification

    Domain: Eukarya

    Kingdom: Animalia

    Phylum: Chordata

    Class: Mammalia

    Order: Primates

    Family: Hominidae

    Genus: Homo

    Species: sapiens

    Part 1: The assignment document contains a table with images. The images are examples of nine Animal Phylum: Porifera, Cnidaria, Nematoda, Athropoda, Platyhelminthes, Annelida, Mollusca, Echinodermata, and Chordata.
    There are 9 Organisms in Nine Different Phyla.

    Organism Phyla Dichotomous Key (steps) Classification

    Use the Dichotomous Key to determine the taxonomic category (phylum or class as shown on the key) for each animal (picture), and write these categories under the Classification Column on the table.

    You will also need to list the phylum for each animal picture in column one; and list in column 2 all the steps chosen when using the key to arrive at the classification for each animal.

    1. Which phyla lack organs? What type of symmetry do they have?
    2. List all of the phyla that show cephalization?
    3. Do all organisms on the table have 3 germ layers (endoderm, ectoderm and mesoderm)? If not, which Phyla have fewer than three germ layers?
    4. One phylum has more species than all the others. State the name of this phylum and provide several different examples of species found in this phylum.
    5. According to chapter 24, fish do not all have the same skeletal structure? Describe the differences among fish from the most primitive to more advanced types.
    6. Describe the three types of mammals based on how their young develop?
