The Plesiosaurus, a remarkable prehistoric sea - reptile, mainly dined on fish. What set this dinosaur apart wasn't just its long neck but its unique swimming style. Instead of rowing with its paddle - shaped fins, it propelled forward by flapping them like wings, similar to a sea turtle.

While the Plesiosaurus is a prehistoric creature and not something you can use in the traditional sense, if you're a collector or enthusiast, you might have a model or figurine. Display it in a well - lit area to show off its details. Keep it away from direct sunlight to prevent color fading. If it gets dirty, gently wipe it with a soft, dry cloth. Don't use harsh chemicals as they could damage the surface.
