I. Title: Animal Phyla Survey

II. Purpose: To observe representative animals from various animal phyla

III. Materials: 24 preserved animal specimens

IV. Procedure: 1. First identify any one organism’s name. 2. Then find out the phylum that the organism is in. 3. Identify whether the organism is either a vertebrate or an invertebrate. 4. Write down a couple characteristics such as the symmetry, endoskeleton or

exoskeleton, asexual or sexual reproduction, or the blood circulation. 5. Finally write down any general observations and repeat all the steps. 6. When the final organism is done, move on to the analyze and conclude questions.

VI. Analyze and Conclude: 1. Compare and contrast any 2 invertebrates. 2. Compare and contrast any 2 vertebrates. 3. Compare and contrast an invertebrate and a vertebrate.

VII. Answers:

1. The horse fly has bilateral symmetry while the sand dollar has radial symmetry. The horse fly has an exoskeleton while the sand dollar has an endoskeleton. They have different way of circulating blood. They both have many legs. They are both not that big in size. They both do not have a back bone.

2. The chicken and the pig embryo are different in color. The chicken embryo has 2 legs and 2 wings while the pig embryo has 4 legs. The pig embryo is bigger than the chicken embryo. They both have bilateral symmetry, an endoskeleton, and a closed circulatory system. They are both chordates. They are both crouching.

3. The turtle is a chordate because of its backbone. The painted lady does not have a backbone and is an arthropod. The painted lady has an exoskeleton, an open circulatory system, and bilateral symmetry. The turtle has an endoskeleton, a closed circulatory system, and bilateral symmetry. They both have bilateral symmetry. They can both move and they can both be small compared to other animals.
