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
Scientific
name: Homo 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.

Download Dichotomous Key Key
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.
For
help on how to use the Dichotomous Key, download and review the document
called How to use the
Dichotomous Key.
Save
a copy of the table with your name in the file name.
Part
2: Using text Chapters 23 and 24 answer the following questions as it relates
to the nine phyla in the assignment table. (Porifera, Cnidaria, Nematoda,
Athropoda, Platyhelminthes, Annelida, Mollusca, Echinodermata, and Chordata.)
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?
