Preserved Specimen: Dogfish Shark, 22-27 Inches, Vacuum Packed

Anatomy Lab’s Preserved Dogfish Shark provides both detailed external and internal anatomical parts to study and observe. Compared to other vertebrates, this shark specimen has a skeleton completely made up of cartilage. Aside from its organs and organ systems, this specimen offers great insights into the body musculature necessary for their habitat.

Due to its complex external parts and internal anatomy, this dissection specimen is perfect for students studying anatomy, comparative anatomy, physiology, biology, or marine biology. Learn how the effects of evolution and ecology have affected dogfish sharks and other vertebrates, including humans. Anatomy Lab’s Dogfish Shark Specimens are 22 – 27” in length, an ideal size for easy dissection and detailed observation of internal systems.

Injection Type: Plain-Injected

Plain-injected specimens have not been injected with colored latex, so the arterial, venous, and hepatic systems are presented in their natural colors.

Shipping Notice:

Preservation Process:

Formalin is the most widely used, economical, and effective fixative used in preservation. Our supplier utilizes a low concentration (3.7%) to effectively preserve the entire specimen and prevent decay. After fixation, specimens go through a series of washes to remove residual formalin. The amount of residual formalin remaining is usually less than 1%, which is in line with the federal OSHA standard for formaldehyde LTL exposure of 0.75 ppm over an 8-hour period. Specimens are then stored and packaged in the supplier's non-toxic, non-formaldehyde holding solution. This solution inhibits decay, fungal and bacterial growth, and prevents desiccation of specimen. Specimens are never shipped in formaldehyde.

Properly Care for Your Specimen

Anatomy Warehouse recommends that you keep your specimen wet with holding fluid every time you use it. A pail or jar will ensure the longevity and usability of your specimen.

While dissecting your specimen, spraying the specimen with holding fluid will help keep it moist, allowing you to maximize your time with the specimen.

After dissection, spray your specimen generously with holding fluid before storing it in an air-tight container. By following these guidelines, you can reduce the number of air particles on the specimen and help inhibit mold growth.

Properly Store Your Specimen for Longevity

Unopened specimens are guaranteed to stay fresh for up to a year. With proper storage, this specimen can last for years if stored out of direct sunlight and kept at room temperature.

Opened specimens are under no guarantee. Once a specimen is opened, it is up to you to care for and store the specimen properly to extend its life. Typically, our specimens will last a couple of weeks when properly cared for.
