This extra-large preserved plain grass frog has a 4.5" to 5.5" body length. This plain grass frog specimen provides an affordable and straightforward dissection experience, as its size makes the internal organs and external structures easy to locate and identify. The genus and species of this grass frog is typically Rana forreri.
Frog dissections provide the opportunity to study physical anatomy, and can even help students better understand aspects of frog reproduction and life cycle stages, such as the transformation from tadpole to adult frog.
Plain grass frogs are wonderful first-time dissection specimens. Whether in a middle school, high school, or college biology lab, frog dissections give students memorable learning experiences that help deepen their respect for the complexities of life.
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.
