Double-Injected Grass or Leopard Frog Dissection Specimen for Biology Labs | Vertebrate Anatomy

Due to a national shortage in the frog supply, these are currently unavailable.

This grass frog dissection specimen is an excellent choice for activities requiring the dissection of a vertebrate animal and is widely used in middle school and high school biology labs to study vertebrate anatomy and organ system organization. Frogs are ideal model organisms because their body systems are clearly defined and easy to compare to other vertebrates. Each specimen has a body length of approximately 3–4 inches (legs not included) and is specially preserved. This specimen is plain (not dye injected). If you are looking for a dyed specimen to highlight the circulatory system, we offer double-injected specimens here.

Did You Know? Frogs do not chew their food. Instead, they use their eyes to help push food down their throat—when a frog closes its eyes while swallowing, the eyes press inward to assist the process.

Store specimens in an area of room temperature away from direct sunlight. Do not freeze or expose to high temperatures (more than 85ºF). Specimens will last up to 12 months when left unopened. After opening, the specimen should be placed in a zip-top bag and may be kept for up to one month.
