Preserved Spiny Dogfish Shark (Squalus acanthias) — Cartilaginous Fish Anatomy Specimen
Item Includes: 1 vacuum-sealed preserved Spiny Dogfish Shark (Squalus acanthias)
The Spiny Dogfish Shark (Squalus acanthias) is a classic teaching specimen for vertebrate and elasmobranch anatomy, offering students a close-up look at one of the ocean’s most fascinating cartilaginous fish. This preserved shark provides a detailed view of features like spined dorsal fins, a flexible cartilaginous skeleton, and a massive oily liver used for buoyancy instead of a swim bladder.
Perfect for classroom dissections, homeschool science kits, or museum exhibits, this specimen highlights both anatomical and behavioral adaptations found in marine predators. Students can explore evolutionary connections between sharks and bony fish, and study unique physiological traits that have helped sharks thrive for over 400 million years.
Educational Features
Cartilaginous Fish Anatomy: Study fins, gills, vertebrae, digestive system, and reproductive structures.
Shark Sensory Systems: Observe the lateral line and Ampullae of Lorenzini, specialized organs that detect vibrations and electrical fields.
Evolutionary Insight: Learn how the dogfish shark’s design exemplifies ancient vertebrate traits, including internal fertilization and long gestation (up to 24 months).
Classroom-Ready: Each specimen (8–12”) is preserved in formalin, vacuum-sealed, and ready for immediate use in labs or displays.
Sustainably Collected: Responsibly sourced from the Gulf of Maine by Tidepool Tim of Gulf of Maine, Inc.
Common name: Spiny dogfish, cape shark, spur dog
Scientific name: Squalus acanthias
Locations: Open ocean
Seasonality: Available year-round
Colors: Gray
Size: 8–12”
Collected: Deep sea fishing
Quantity: Sold by the each
Note: This is a preserved marine specimen. Natural variations in size, color, and appearance from photos should be expected.Item Includes: 1 vacuum sealed spiny dogfish shark (squalus acanthias), free shipping included
