Earthworm, 9-12", plain specimen

Item# PM-WORM

Our preserved earthworms are an extra-large 9-12” size so dissecting them is easier. You can study the digestive, circulatory, reproductive, and nervous systems of the earthworm. 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.

Great product! Review by
I ordered this as an additional specimen to our Apologia biology dissection kit for our lab group. This worm was actually a better specimen than the one included in the kit.
Great Review by
Item was as described and was in great condition. Have bought specimens from other companies and they were not as well preserved as these (some were dried out). Recommend.
Great Specimen Review by
The earthworms were just the right size and very easy to dissect. The high school teens in my homeschool co-op were able to easily cut thru them, and begin identifying all the organs.
Excellent Annelidas! Review by
This is the 4th year dissecting with HST's excellent earthworms. Always large & firm, students are easily introduced to the, sometimes scary, task of specimen dissection with these quality products.
Excellent specimen Review by
The worm was in great condition, and it was a worthwhile dissection to do. Good learning experience. We are thankful your company exists and that your products are of good quality.
