A sea animal that closes a deal? A singer who needs closure? Or a navy force that secures letters?

Used to contemplate or have fun. My parties are known worldwide. While my waving is constant, some stop to see a world in a piece of me.

Filled with precipitation, And not to boast, The most diverse biome. Finer roast.

You mostly know me in my synthetized and comercialized form, but but you should know me as an animal useful for filtering the sea - just like you know that I can clean your skin or your countertop.

Ain’t nobody cool as me unless they’re known for being level headed. Long and green, crunchy and delicious. Sweet or sour, sometimes that bite can be vicious.
