Animal Specimen Set of 7, Large

This set of seven large-sized preserved specimens is a great way to learn about and compare the anatomy of several animals. The specimens are larger than those typically found in a set like this and provide a better dissection experience because it is easier to locate and identify the internal organs and external structures.

The seven preserved specimens in this set include a grass frog (3.5"-4"), earthworm (8"-10"), large Lubber grasshopper, crayfish (4"-6"), clam (4"-5"), perch (7"-9") and starfish (3"-6"). None of these specimens are injected. This set includes all seven specimens packaged together in one bag.

Note: Specimens are initially preserved with a formaldehyde solution, the best animal tissue fixative. The formaldehyde is then displaced first with water and finally with a glycol solution to produce a moist, low-fume specimen which will not decay over time.

In sealed, original packaging, our preserved specimens are guaranteed to remain fully preserved and free of decay for six months from the date of purchase.

Once the original package is opened, use specimen within one month. For best results, observe the following storage procedures:

• Store specimen in heavy-duty, zip-lock bags to minimize drying between dissections.
• Specimen will slowly dry out or become contaminated in zip-lock bags; add a teaspoon of Specimen Holding Fluid to retain moisture.
• Freezing or refrigeration is not necessary and may damage fragile tissues.

Crayfish specimen will include at least one cheliped to dissect; although, in some cases, it may be detached from the body.
