Invertebrate Survey Set , preserved, 9 phyla, 16 species.
Use specimens as teacher demonstration models or for dissection by students working in groups at separate stations. The Invertebrate Set includes representative specimens across 9 phyla (16 species) designed to help students gain a better understanding of the diversity of invertebrate organisms and the shared characteristics found along taxonomic lines.
Students compare internal and external structures and make observations about the respiratory, digestive, circulatory, and reproductive systems, if present, for each specimen.
The teacher's manual contains extension activities and a reproducible blackline master student guide. The student guide contains background information, dissection guides for each of the animals and protozoa, and reflection questions.

Carosafe Preserved Specimens
Carosafe® is Carolina Biological's proprietary shipping and holding fluid for specimens that have been previously fixed in formalin. Although specimens are first preserved with a formalin solution, they are then washed and placed in formaldehyde-free Carosafe®. Holding the specimen in Carosafe® reduces the presence of formaldehyde residues left over from the initial preserving process, thereby diminishing or eliminating unpleasant odor. This produces a formalin-preserved specimen that, when dissected, minimizes student and educator exposure to formaldehyde.
Carosafe® specimens should be washed before use and dissected in well ventilated rooms with appropriate hand, eye and body protection.
