Grass Frog / Leopard Frog Specimen

Double-Injected Grass or Leopard Frog Dissection Specimen for Biology Labs | Vertebrate Anatomy This double-injected grass or leopard 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 prepared with red latex injected into the arteries and blue latex injected into the veins to clearly display the circulatory system, allowing students to observe organs and blood vessels simultaneously during hands-on classroom dissection.
