Frog, grass, 3-4"
This medium preserved grass frog specimen has vessels single injected with red latex. Genus and species is typically Rana forreri.
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 can be stored almost indefinitely. We recommend that you use specimens within one year of purchase to ensure the best tissue quality. Specimen discoloration over time is normal and does not indicate decay.
Store your specimens at normal room temperature--refrigeration is
not required. Storage in attics or garages at high temperatures will damage the specimens. Once opened, specimens can be resealed in a Zip-lock bag to prevent them from drying out for later use.
Shipping Note: This item only ships to a street address in the 50 US states with Standard or UPS shipping options.

Great for my class Great frogs! I ordered 5 for my class and they were lots of fun. The order came earlier than expected (even with UPS ground) and the specimen size was very good and more than useful (larger than I had anticipated)

Great specimens
Reviewed By: Jennifer
This was my first time with frog dissection. I used the frogs to dissect after our study of the human anatomy. The frogs were a very good size--bigger than I had expected! My 5th graders were very involved with the dissection and learned a lot! I will be ordering more frogs next year.

Excellent Class Project
Reviewed By: 4th Grade Teacher
I decided to try a frog dissection with my fourth graders as an enrichment project prior to Spring Break! The specimens were great, and my students were very intrigued with the anatomy! I was thrilled with the size of the frogs, the order came quickly, and I would definitely order from your company again!

Nice Specimens
Your dissection specimans are very nice. Your frogs in particular tend to be larger than some from other mail-order companies and that makes dissection much easier.

Great Experience
Very fun!! We found some insects in the stomach. We were also able to extract the brain from the skull (very tricky!!). It is very cool how the 3-part liver fits together. We were able to identify it as a female frog. If it weren't for the formaldehyde, we would have devoured the legs!!
