Preserved Spiny Dogfish Shark (Squalus acanthias), 8-12 inch Authentic Formalin-Preserved Specimen for Dissection, Marine Biology Study, Anatomy Education, Science Classroom & Lab Learning

Features

• Cartilaginous Fish Anatomy Preserved Dogfish Shark: 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 a swim bladder. Learn about their long lifespan (up to 100 years) and 2224 month gestation period.
• Enhanced Sensory Exploration Study the sharks advanced sensory systems, including the lateral line that detects water vibrations and the Ampullae of Lorenzini, which sense electrical fields. These unique adaptations provide deeper insight into shark behavior, navigation, and their role in marine ecosystems.
• Perfect for Lab & Classroom: Each spiny dogfish shark measures 812 inches, preserved for long-term use, and sealed for freshness. Supports 12 students per dissection. Collected sustainably from the Gulf of Maine by Tidepool Tim.
