What's inside a shark? We don't actually know, but the TEDCO Toys 4D Vision Great White Shark Anatomy Model should give you a pretty good idea. This realistic model includes a thirteen-inch great white body with twenty detachable organs and body parts. The illustrated assembly guide shows you how to deconstruct and replace the parts, all while explaining the name and function of each piece. This neat learning model includes a platform for easy observation and display.
