Authentic 1950’s Seguso Archimede Murano Art Glass Stingray Sea Animal

It’s a authentic Seguso Archimede art glass sea creature but I’m not sure what kind.I thought it might be a stingray or manta ray but the tail isn’t long enough so maybe it’s a mollusk.It’s a beautiful color of green with controlled bubbles that are perfectly aligned,balanced and symmetrical that go out to very edge of the glass.It’s from the 1950’s and had a sticker on it like the one on the Barbini pear I have pictured that was so far gone you couldn’t read it anymore so I took it off.
