This is the Umino or Ocean tamagotchi. This is the Japanese version. He is a very, very tough tamagotchi to take care of. I sometime find him dying for no apparent reason. But still, I recommend him in every collection. The characters are very cute. You must also safeguard this one with your life like the Morino because a polar bear will attack you little guy if you do not scare him away in time by tapping the case. One attack will equal death for the Umino.
