Grass Frogs, Preserved for Dissection

Product Details

Lithobates (formerly rana) pipiens. This affordable and popular specimen is well-suited for the study of basic vertebrate anatomy and the pattern of organ systems. Presented as an intermediate between fish and mammals due to its semi-aquatic nature and also the presence in amphibians of a three-chambered heart. The circulatory system is thus incompletely divided into pulmonary and systemic circuits. Measurements from nose to cloaca. Sizes as indicated.
