         SHARK, FROG, AND FETAL PIG COMPARITIVE ANATOMY LAB

Purpose: The purpose of this introductory lab is to gain valuable laboratory and
dissection experience. It is also meant to follow up a basic understanding of body
systems with comparing these systems in a fish (Squalas acanthias), an amphibian
(Rana pipiens), and a fetal pig (Sus scrofa)

Prelab – It is imperative that you learn as much as you can about the body systems
of these organisms prior to the day of dissection. I have enclosed some basic
information on some body systems, but you need to do your homework and come
into class with an understanding of crucial organismal differences.

Method: There will be a three-day dissection, following the laboratory and safety
guidelines presented each day in class.

Analysis and Discussion – In college essay format, you will compose a paper that
compares and contrasts the different body systems found in each of the three
specimens studied. Any source used should be included in a bibliography. Your
paper may include diagrams and/or sketches to better explain the physiology of the
organism. It should go into detail comparing and contrasting the anatomy and
physiology of each organism. Animal behaviors and habits must be analyzed for an
understanding of the overall physiology of an organism. (FORM FITS
FUNCTION) For example (in the circulatory system) the fish heart is two-
chambered, while the amphibian heart has three chambered, and the mammalian
heart has four chambers. This feature is one of many that should be analyzed and
discussed. (In other words, how does each work for that organism)
