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 price. Review by
My daughter hasn't dissected this yet but it looks like it is a great specimen.
Earthworms Review by
The earthworm specimens are excellent! I used the specimens for a summer program with DECATS. There was no problem with odor. The earthworm was large enough to dissect for a group of 5-6 scholars.
Excellent specimen Review by
I ordered this to use with an Apologia Biology lab for my 10th grade student. It was large, which allowed for easy dissection. Plan to order ALL our dissection materials from Home Training Tools now!
Earthworms Review by
I needed more earthworms for the 3rd and 4th graders to use and this batch was just as good as the others I purchased. Fresh and fat...easy for the younger hands to manage and open correctly
Earthworm 9-12" Review by
These were great specimens for my needs. Teaching 3rd and 4th grade Enrichment Science, these were big enough for the students to handle and use in our dissecting project to understand worms and their body. They were all FAT and large enough for small hands to handle well.
