This is Satoshi Kamiya's Eagle Ray. It's a pretty basic model with a very interesting fold used to design the two blunted nose ends. I rather like the model because as basic and uncomplicated as it looks here, it looks the same in the book (just using nicer paper) And the view from underneath is essential (according to Satoshi) to understanding and appreciateing the model. I agree 100%, except that the eyes on mine dind't really come out as nice as his, so you're losing some of the effect. The gills are just as nice though. Enjoy!
