• Crayfish Activity Set


    Cornerstone's preserved crayfish are perfect for classroom work.

    The specimen is conveniently vacuum-sealed to stay fresh for up to 6 months. Our crayfish are shipped with a small amount of low-odor holding fluid (not formaldehyde or formalin) to keep them fresh.

    After opening, the crayfish may be kept in a plastic zip bag and should be used within one week. The crayfish are between 4 and 6 inches in length.

    In addition to crayfish, this activity pack includes the following:

    • Large plastic forceps

    • Wooden probe

    • Foam dissection tray

    Purchase as a single pack with one of each item above


    Purchase multi-packs of 10 crayfish dissection activities for a 10% discount.

    Don't forget to include magnifying lenses, vinyl gloves, and Cornerstone's great Lesson Plans (CC week 7; available on or before July 1) to complete your activity!
