Snake, Garter or Water, plain specimen
Learn about internal snake anatomy! This preserved snake specimen is usually from the Genus Thamnophis
, although the species varies. 18-22" long. Not injected.
Note: Snake dissection 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 snake dissection specimen which can be stored almost indefinitely. We recommend that you use preserved snake specimens within one year of purchase to ensure the best tissue quality. Preserved snake specimen discoloration over time is normal and does not indicate decay.
Store your preserved snake specimen at normal room temperature--refrigeration is not
required. Storage in attics or garages at high temperatures will damage the specimens. Once opened, snake specimens can be resealed in a Zip-lock bag to prevent them from drying out for later use.
Note: This item only ships to the 50 US states with Economy, Ground or Express shipping options.

My biology students rate these as a "10"! We had several females that were full of fertilized eggs. The specimens were large and structures were easy to identify. Absolutely worth the cost. Best dissection of the year.

The snakes were great. My co-op class loved dissecting them. Definitely the favorite dissection so far. My only issue was with the huge variation in the size of the snakes. The description says 18-22 inches, but we had one that wasn't even 10 inches. The others were all at least 24 inches, but when working in pairs, a 10 inch snake was a bit small and I ended up having to have a couple groups of 3 so that everybody could see what was going on.

I have ordered these snakes for dissection for my veterinary technician students for the last four years and it is one of our most popular and memorable labs! It is one thing to lecture on the differences between mammal and reptile anatomy but when you ACTUALLY see how everything fits in the elongated body it is amazing! There has only been one time that we received small snakes, in the rest of the shipments, including the last one, the snakes were down right enormous! I can't tell you how much I appreciate the online dissection guide and the images!! Especially when I have a large class. As for pricing on these specimens and your other products, I'm as pleased as can be!!

My kids LOVED dissecting this snake. I'm not into snakes so I don't handle them. It was fascinating to spend time up close to a snake, since I would not if it were not dead, and actually study it! I highly recommend the snake as a fascinating dissection specimen - especially for those of us who run from them otherwise :)

The students enjoyed dissecting these snakes. The first snake was pregnant and we were able to dissect the eggs to see baby snakes. Very neat! We were disappointed with the second snake as it was small and hard to see anything. I definitely recommend sending only the larger snakes.
[Home Science Tools adds: Unfortunately, the size of our snakes does vary slightly, depending on what we get from our supplier. You'll be able to see the important parts on any size, though.]
