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.
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
Product Features

- Immersed in Carosafe® holding fluid, packaged in pails, and sealed with leak-proof, reusable lids; ideal for long-term storage
- Price listed is 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. Learn More.
NOTE: Based on seasonal availability, substitution of shark genus and species may occur. Possible substitutes include the brown smooth-hound shark (Mustelus henlei) and the Atlantic blacktip shark (Carcharhinus limbatus). Dissection protocols and internal anatomy are the same as the traditional dogfish shark.
