Earthworm, 8-10", plain specimen
Study the digestive, circulatory, reproductive, and nervous systems of the earthworm. Plain (not injected) preserved dissection specimen. Earthworm species is Lumbricus terrestris
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.
Note: This item only ships to the 50 US states with Economy, Ground or Express shipping options.

- Friday, April 26, 2013Earthworm DissectionReviewed By: Jodi
By carefully dissecting this earthworm, you can view its digestive, circulatory, reproductive, and nervous systems. Purchase the guide and dissection tools separately, and be sure to add extra pins, as they are invaluable. Dissection teaches attention to detail, careful following of directions, and respect for the life of the specimen. It is truly wondrous to see how intricate even the lowly earthworm is. Recommended.

It was a thick earthworm which made it easier to dissect and study its organs.
