  • My Middle School students love to dissect these worms because they are easy to handle. Also, they do not have a strong smell which helps with my more squeamish participants.

      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. 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.

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