Z55  This twice life-size replica of a female Rana catesbeiana is a wonderful complement to hands-on dissection.  Because she includes vivid details such as internal nares, vomerine teeth, eustachian tube, and nictitating membrane of the eye, students can develop a clear generalization of what they have found while dissecting their own specimen.  Non-breakable, the bullfrog detaches from its base for hands-on examination. Over 175 hand-numbered features identified in the accompanying key, which also includes an illustration of the male reproductive system.  20"x14"x4" inches   53 x 38 x 10 cm.
