More Information

Earthworm, 8-10", plain specimen

Item# PM-WORM

Study the digestive, circulatory, reproductive, and nervous systems of the earthworm. Plain (not injected) preserved dissection specimen. Earthworm species is Lumbricus terrestris (nightcrawler).

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. 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.

nice worm Review by
great price, nice product!
Great teaching Worms Review by
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.
Really Big Worms Review by
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!
Almost what we expected Review by
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+.
Excellent Review by
HST specimens are consistently of better quality and size then other suppliers. Customer service is the best in the business and shipping times are the fastest also!
