Discover annelid anatomy with Cornerstone's preserved earthworms. 

An excellent choice for any activity requiring dissection of an annelid (including earthworms and leeches). Students can observe and document external structures (such as segmentation, setae, and clitellum). Internal anatomy includes the nervous, digestive, circulatory, and reproductive systems.

Specimens are individually vacuum-sealed. Initially preserved in formaldehyde to fix tissues. Specimens are then rinsed with water and packed in a low-odor, non-toxic holding solution. 

Store specimens in an area of room temperature away from direct sunlight. Do not freeze or expose to high temperatures (more than 85ºF). Specimens will last 12 months when left unopened. After opening, the specimen should be placed in a zip-top bag and may be kept for up to one month. 



*Available in singles with a discount once you purchase 10 or more. 

**This item includes earthworm specimens only. Tray and dissecting tools sold separately. For tools and other items, see our Earth Worm Specimen Dissection Bundle
