Turritella Shell – Spiral Marine Specimen
This natural turritella shell features a long, tightly coiled spiral form that makes it an excellent specimen for studying shell structure and growth patterns in homeschool and classroom marine science lessons. Its distinct high-spired shape allows students to observe repeating whorls and incremental shell formation.
Students can examine the elongated cone structure, fine ridges along the surface, and the gradual expansion of each spiral turn while discussing marine habitats, mollusk classification, and shell composition.
