DESCRIPTION

Bullfrogs provide a better dissection experience than grass frogs because of their larger body mass, better-defined organs, and well-developed muscle structure. This huge preserved bullfrog specimen in double injected and has a body length of 5"-6".

Arteries are injected with red latex and veins are injected with blue latex to easily trace the vascular system. Internal organs and muscles are easy to locate and identify. The bullfrog species is typically Rana catesbeiana.

Whether in a middle school, high school, or college biology lab, frog dissections give students memorable life science experiences and are wonderful first-time dissection specimens. Dissecting a frog is a great hands-on activity for teaching biology and environmental science in the home and science classroom.

10+ pricing is based on bulk-packed specimens. When necessary, you will receive a combination of 10-packs and individually packed specimens to fill your order.

Note: Specimens are initially preserved with a formaldehyde solution, the best animal tissue fixative. The formaldehyde is then displaced first with water and finally with a glycol solution to produce a moist, low-fume specimen which will not decay over time.
