How are the eyes positioned in the frog's head in comparison to the positioning of persons eyes?

Human eyes are positioned on the sides of the nose, 1/3 of the way down the face. The frogs are positioned on the top 1/3 - enabling them to look out of the water without coming all the way out. The bulge also assists them in looking all directions at once.

The frog's eyes also make it swallow. This is why they blink and pull their eyes in when eating food.
