Whether in a middle school, high school, or college biology class, frog dissections give students memorable life science experiences. Dissections are wonderful hands-on activities for teaching biology and environmental science in the home and in a classroom.

Find scalpels, dissecting pans, and other essential dissecting tools to begin your hands-on exploration of frog anatomy!

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.

  • Freezing or refrigeration is not necessary and may damage fragile tissues.
