A Frog Riding a Beetle: Is This a Real Wildlife Photo or a Bunch of BS?

Question #2. Can the frog’s mouth remain open in so many of the shots?
Frogs could possibly open their mouths like what’s seen in the photos, but aside from when they are eating something, it is a sure sign of distress. The only time when the frog had its mouth open naturally is when a frog is incredibly distressed — like when it’s being eaten by a snake.
