Reader Charles Jones sent a hidden amphibian. His notes:
Attached is a photo taken by my daughter Hannah Jones near the “Grand Canyon of Pennsylvania”. This is a case in which the critter is impossible to see, until you see it. And then it is obvious.
Well, I’d call it “medium difficulty” but we’ll see. Answer at 11 a.m. Chicago time. Can you spot the frog?

Got it. It had me going for a second, though.
Thank you! That was fun.
Oops, thar she be!
I was going to quip “under those leaves” but then I saw the little fellow.
I don’t know how you people do these things. I’ve never found a single one of the animals posted in these confounding Highlights for Adults searches!
Either I don’t have the patience, or I don’t have the skill. OK, I definitely don’t have the patience, but I probably also don’t have the skill.
But I did find a leaf with a fish face!
Double click to enlarge the image, and use your scroll bars to scan up and down, left and right. It is well camoflaged, but you can see this one.
I tried that, to no avail. But see if you can find my fishy-faced leaf.
Got it relatively easy. The problem is to use the good mental scale. I was first looking for a more or less leaf-sized frog.
Exactly my experience! I was looking for something much bigger. Right up until I finally saw the little guy. 🙂
Don’t see him. He must have went a courtin before I got here.
It’s either pareidolia or it’s looking right at me in the middle.
Ah, OK that one’s a). Went back and found the actual frog right away.
I found it on the enlarged picture, then went back to the small version and lost it again.
One problem that slowed me down finding it was that I was looking for a Wood Frog, not a Spring Peeper. Wong expectation.
Once I knew from the comments it was smaller that leave sized it was easy.
than leaf
I got lucky…just looked right at it and realized it was a frog. That hasn’t happened before.
