This medium single injected preserved grass frog specimen has a body length of 3.5" to 4", large enough to see all the internal organs and external structures.
Use dissection tools to explore frog anatomy! The arteries are injected with red latex to make it easier to trace the vascular system. The medium size and single injected vessels of this preserved frog specimen provide a good balance between enhanced dissection experience and cost.
The genus and species of this preserved grass frog is typically Rana forreri.
Whether in a middle school, high school, or college biology lab, frog dissections give students memorable life science experiences and are wonderful first-time dissection specimens. Dissecting a frog is a great hands-on activity for teaching biology and environmental science in the home and science classroom.
10+ pricing is based on bulk-packed specimens. When necessary, you will receive a combination of 10-packs and individually packed specimens to fill your order.
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.
