The sea urchin is called uni in Japanese and if you get it at some of the top sushi restaurants, especially those around a fish market, you'll never believe this ball of black spikes could hide such an amazing taste inside! The 3D Sea Urchin Dissection Puzzle lets you find out exactly how this unique sea creature is made and is a very useful tool for teaching children about marine biology.
The 3D Sea Urchin Dissection Puzzle is made of PVC and consists of seven parts: two parts are the black spiky exterior and five are the urchin's meat, the uni you get at the sushi restaurants or at food stalls in summer festivals. It looks easy but each piece has its own, unique position, so putting it in its place and assembling the whole thing takes some skill and dedication that all children will appreciate. And lovers of Japanese cuisine!
