    Great Specimens

  • I ordered two of these for my sons to dissect. They came in great condition and were a nice size for viewing internal organs. A wonderful first dissection item for any middle-schooler.

  • The worm I ordered was to be our first ever dissection. It arrived on time and looked like, well, like a gray worm. We were pleased that there was almost no odor and to our surprise, we were able to locate almost every "part" that our BJU Biology curriculum instructed us to find.

      Earthworm, 9-12", plain specimen

      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.

      HST Specimen Guarantee

      In sealed, original packaging, our preserved specimens are guaranteed to remain fully preserved and free of decay for six months from the date of purchase.

      Once the original package is opened, use specimen within one month. For best results, observe the following storage procedures:

      • Store specimen in heavy-duty, zip-lock bags to minimize drying between dissections.
      • Specimen will slowly dry out or become contaminated in zip-lock bags; add a teaspoon of Specimen Holding Fluid to retain moisture.
      • Freezing or refrigeration is not necessary and may damage fragile tissues.

      Shipping Note: This item contains preserved specimens and only ships to a street address in the 50 US states.
