The 4D Dolphin Model is a fun and instructive tool for curious children and adults alike. It includes 18 parts to put together that provide a view into the inner workings of this sea-dwelling mammal when completed. The pieces are hand-painted and detailed showing the structure and placement of a dolphin s skeleton digestive system and other organs. A durable stand is included for showcasing the desktop-sized model. The animal anatomy model is recommended for ages 8 and up and is suitable for use in the home as well as schools and other educational institutions.
