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.

Excellent specimens Review by
For the most part we have found these earthworm specimens to be of high quality. Occasionally we receive a specimen which differs somewhat from the others--may be a little longer or shorter--but usually the organs are just as identifiable.
specimen old? Review by
I purchased 2 earth worm specimens for my biology class and one came in excellent condition, but the other seemed almost decayed. The organs were indistinct and crumbly and hard to identify.
Both orders were packaged and shipped quickly and well.
Fantastic Dissection Worm Review by
I ordered a lot of these for a homeschool co-op dissection. This is a great beginner dissection specimen. It is large enough to identify everything inside the worm, but small enough that it won't gross everyone out (much). The kids loved it. We will be ordering these again. Be sure to order the dissection guide (cheap and worth it). The specimen goes perfectly on the Styrofoam tray that HST offers.
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.
