Do Triceratops fly like Helicopters?
Do Pteranodons shoot their beak out?
Oda doesn't care about IRL biology. There's a reason why even normal attacks can injure the Ancient Zoans. They don't have what Kaido has and they certainly don't need Shockwaves to bypass their "hides", normal attacks would suffice.
King is special since he has something else entirely, not a "hide".
Queen isn't.
