This is with regard to the the post where I was talking about the design of the visual system for predators and prey. I had taken an example of a chameleon for my explanation but could not photograph it on time :(. A frog never the less is an equally good specimen for this dual role played by many creatures in nature. Moreover, I had got a really good side shot of a frog when I had been to Agumbe and wanted a reason to share it. At that time I didn't know I would be coming up with this blog, or would have photographed the FV also. I thank Kalyan Varma for allowing me to use the FV of the frog captured by him here.
Observe the design of its face and eyes. The eyes are placed at almost 45 deg to the face. In the side view it can keep an eye on almost one complete side of its body and watch out for predators.
In the front view you can see that they still have some room for common visual region in order to perceive depth which will be used to strike the prey with their tongue.
