Sun Dolphin Boats Miami Dolphin's Helmet Logo Question?

Miami Dolphin's helmet logo question? - sun dolphin boats

I have a bet with a friendly over the logo on the side of the trunk of dolphins.

(A dolphin in the air with a helmet with an "M" on the side.

The question is: What is the substance of the dolphins?

Is this a circle of fire that goes with the dolphins?

Or is the sun? (Florida, who is known for the sun.)

I think it is ..... the sun, but my friend disagreed.

Love to hear your opinion. Thank you!
