Earthworm, 8-10", plain specimen
Study the digestive, circulatory, reproductive, and nervous systems of the earthworm. Plain (not injected) preserved dissection specimen. Earthworm species is Lumbricus terrestris
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. Plan to use specimens within one year of purchase to ensure the best tissue quality. Specimen discoloration and dryness 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.
Note: This item only ships to the 50 US states with Economy, Ground or Express shipping options.

My kids are 10 and 11 and really enjoyed dissecting these worms.
The chemical that preserves them did not have a strong odor and the worms were big enough for us to identify the internal and external parts.
We used the dissection guide from homesciencetools.com to help us through the process and it was invaluable.

These worms are really huge...for a worm, of course. They will be easy to dissect and the organs should be large enough for my high school freshmen to find and label. Thank you for the quick shipping too!
- Saturday, October 12, 2013Almost what we expectedReviewed By: R and B
The only thing that shocked us about this was that it arrived...wet. When you see the picture on the internet it looks like it will be rubbery but basically dry. It is sealed nice in a package but in the package there is liquid. This really made us go, "eww." It arrived as promised. We haven't done anything with it yet but are happy with the purchase. The price, time to get it and it being what was advertised, A+.
