Frog Specimen, Grass, 3"-4", Plain

This medium plain preserved grass frog specimen has a body length of 3.5" to 4", large enough to see all the internal organs and external structures. This plain grass frog specimen provides a great dissection lab experience at a low cost. Whether in a middle school, high school, or college biology lab, frog dissections give students memorable life science experiences. Dissections are wonderful hands-on activities for teaching biology and environmental science in the home and science classroom.

The genus and species of this preserved grass frog specimen is typically Rana forreri. 

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.

Please Note: When ordering this product, you may receive our upgraded Single-Injected Frog Specimen at no additional cost to you! The arteries in this upgraded specimen are injected with red latex to make it easier to trace the vascular system.

Important Notice: For orders of 10 or more, there is a chance these specimens could be shipped in a 10-pack. If you require specimens to be individually packaged, please contact our customer service at (406) 256-0990.
