Plain Bullfrog Dissection Specimen for Biology Labs | Vertebrate Anatomy
This plain preserved bullfrog dissection specimen (not injected) is a high-quality educational specimen commonly used in middle school and high school biology labs to teach vertebrate anatomy and comparative anatomy concepts. Bullfrogs are a classic model organism for anatomy studies due to their well-developed organ systems and structural similarities to higher vertebrates. Each bullfrog specimen is preserved to maintain clear visibility of anatomical structures, making it ideal for hands-on classroom dissection. Students begin by examining the external anatomy of a bullfrog, then proceed to explore internal organ systems during dissection.

This preserved bullfrog specimen for dissection supports instruction in vertebrate biology, physiology, and organ system function, making it an excellent choice for anatomy labs, life science courses, and homeschool science programs. Pair it with a bullfrog dissection kit that includes tools, a dissecting guide, and a tray for a complete lab experience. Specimens are initially fixed using a formaldehyde solution to preserve tissue structure, then rinsed and stored in a glycol-based solution, producing a moist, low-odor, long-lasting specimen suitable for educational use.
Did You Know? Bullfrogs have a three-chambered heart, which helps students understand how circulatory systems differ between amphibians, reptiles, birds, and mammals. Even cooler? Bullfrogs can breathe through their skin using a process called "cutaneous respiration".
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.
Discounts available for purchases of 10 or more frog specimens!
