Product Details
The dogfish shark, a member of the class Chondrichthyes, is a popular dissection specimen in general biology and anatomy courses. It is useful for learning about cartilaginous fish and for studying comparative and vertebrate anatomy. Mature specimens allow for a thorough investigation of adult structures. Larger size options (≥22”) are ideal for students working in pairs or small groups.
Dogfish sharks have many characteristics intriguing to students, including their:
- Cartilaginous skeleton
- Five pairs of gill slits
- Claspers (male only)
- Two-chambered heart
- Spiral intestine
- J-shaped stomach
- Lack of a swim bladder and operculum

- Soaked in Carosafe®, then individually packed and shipped in a vacuum-sealed bag for easy distribution
- Prices listed are for 1 specimen
Carosafe®
Carosafe® preservative and holding solution for biological specimens contains no formaldehyde and is not a tissue fixative. Most Carosafe® specimens were first preserved with a formalin solution and then washed before placement in Carosafe®. Specimens are held in Carosafe® prior to shipment, producing formalin-preserved specimens that, when dissected, minimize formaldehyde exposure.
Note: Due to seasonality, availability of preserved dogfish sharks may be limited.
