• 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.

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

    • Large plastic forceps
