open-mouthed
Jaw hanging low
Open-mouthed describes having one's mouth hanging open, typically from shock, amazement, or awe: The children watched open-mouthed as the magician performed.
The image captures involuntary surprise—the jaw drops before conscious thought catches up.
It can also suggest gaping stupidly or being slack-jawed: He stood there open-mouthed while she walked away.
