(Note:  Some of the illustrations I scanned and then inserted into the document and some of them I took cell phone pictures and sent to my computer via email and then inserted them into the document, just to illustrate that both methods work.  I also cut out some of the pictures and taped them to a separate page in order to include all labels neatly. Note that illustrations are in order of the Laboratory objectives sections (eg. shark before Necturus; or muscles before digestion and respiratory).
