Organisms 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 using a dichotomous
key.
The common taxonomic categories are Domain, Kingdom, Phylum,
Class, Order, Family, Genus and Species (Specific Epithet.) We are
looking at the Phylum and Class categories in this assignment.
Assignment details:
Part 1: The assignment document contains a table with nine
images. The images are examples of nine different Animal phyla: Porifera,
Cnidaria, Nematoda, Arthropoda, Platyhelminthes, Annelida, Mollusca,
Echinodermata, and Chordata.

Use the Dichotomous Key to determine the Class category as shown for
each animal (picture), and write the Class names under the Classification Column
on the table.
List in column 2, all of the dichotomous key steps you chose when using the
key to arrive at the classification for each animal.
You will also need to list the Phylum name for each animal picture in column
one using the nine Phyla listed above. Once you have identified the Class
category for each animal using the Key, look up the correct Phylum category
using a credible reference.

Save a copy of the table with your name in the file name.
Part 2: Answer the following questions as they relate to the
nine phyla in the assignment table. (Porifera, Cnidaria, Nematoda, Athropoda,
Platyhelminthes, Annelida, Mollusca, Echinodermata, and Chordata.)
Which phyla lack organs? What type of symmetry do they have?
List all of the phyla that show cephalization.
Do all organisms on the table have 3 germ layers (endoderm, ectoderm, and
mesoderm)? If not, which phyla have fewer than three germ layers?
One phylum on the table has more species than all the others. State the name
of this phylum, and provide several different examples of species found in this
phylum.
Fish do not all have the same skeletal structure. Describe the differences
among fish skeletal structures from the most primitive to more advanced types of
fish.
Describe the three types of mammals based on how their young develop.
Provide references in APA format. This includes a reference list and in-text
citations for references used throughout the assignment.
