Cartilaginous Fish Anatomy – Preserved Dogfish Shark (Squalus acanthias): High-quality formalin-preserved shark specimen for studying elasmobranch anatomy, vertebrate biology, and species identification. Ideal for classroom dissection, lab study, and marine science education.
Hands-On Shark Biology Learning: Perfect for students exploring sharks, marine vertebrates, and evolutionary traits. Excellent for homeschool science kits, lab activities, and museum education displays.
Explore Key Shark Traits: Study the spined dorsal fins, cartilaginous skeleton, oily liver for buoyancy, and absence of swim bladder. Learn about their long lifespan (up to 100 years) and 22–24 month gestation period.
Shark Senses Up Close: Examine the lateral line system and Ampullae of Lorenzini — sensory organs used to detect vibrations and electrical fields in the water, providing insight into shark behavior and ecology.
Perfect for Lab & Classroom: Each spiny dogfish shark measures 8–12 inches, preserved for long-term use, and sealed for freshness. Supports 1–2 students per dissection. Collected sustainably from the Gulf of Maine by Tidepool Tim.
