Earthworm, 8-10", plain
Study the digestive, circulatory, reproductive, and nervous system of the earthworm. Plain preserved dissection specimen. Earthworm species is Lumbricus terrestris (nightcrawler).
Note: Dissection specimens are initially preserved with a formaldehyde solution, the best animal tissue fixative. The formaldehyde is then displaced with water and then with a glycol solution to produce a moist, low-fume specimen which can be stored almost indefinitely. We recommend that you use specimens within one year of purchase to ensure the best tissue quality. Specimen discoloration 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.
Shipping Note: This item only ships to a street address in the 50 US states with Standard or UPS shipping options.

Wonderful WigglersReviewed By: Lexie Wallace Like most of the comments above, these earthworms were great for our dissection! We even had some five year-old kiddos dissecting and they loved being able to see the various organs with these earthworms! They were not smelly or difficult to deal with at all- Thanks!

Earthworm dissectionReviewed By: Vicki Williams Our Apologia class dissected earthworms that I purchased from Home Science Tools. They were very easy for the students to work with and the internal parts were very visable. Thanks for making our dissection a successful and interesting learning experience.

Great SpecimenReviewed By: Pam I was very pleased with the large size of these earthworms. They were well preserved, did not have a strong odor and the organs were easy to find and identify.

But we thought it needed to be DEAD!Reviewed By: Rebecca I purchased this well in advance of needing it in our science curriculum. It was a HUGE earth worm, so it would have made a great specimen for dissection. Unfortunately, when we finally got to the lesson that required a worm, we discovered that we were to do the experiment with a LIVE worm (don't worry, no cutting or otherwise mishandling of the worm was required). Dang, I would have much preferred working with the dead one!!

Nerve Structure VisibleReviewed By: Mrs. T - (Teacher) These are some of the largest and best preserved specimens I have found anywhere. The students are able to see the inside structures very well. Odor was minimal.

Earth Worms
Large and preserved well. Worms used from elsewhere were dried and small, but these were very good quality.

Fun!
Reviewed By: Alison Harrell
Good sized worms - used for my 7th graders and the kids were able to see all the organs very well - it's impressive to see that worms are more than just 'goo' inside! This was their first dissection and they loved it! I love HST's service and products!

good first dissection
The earthworms were in good condition, not smelly at all, and large enough to see the anatomy pretty well. My boys are 11 and 12, and neither wanted to dissect anything, but both found the dissection very interesting once they got started.

Huge Worms
Reviewed By: Michele Lawson
I ordered these worms in addition to the lubber grasshoppers and my students were impressed with the huge size of these worms. Dissection was a breeze and the organs were extremely visible because of the size, preservation method, and the overall great condition of the specimens.
