This photo was taken in early June in the De Soto National Forest in southern Mississippi. Anyone care to guess what is depicted, and how this pattern came to be? Answer to be posted later...
Update: Kiirsten (see comments) from Ontario (wow!) is right that the little guys are "toadpoles"--probably Bufo terrestris. Click on the image for more detail. But it's a drying puddle in a clay-sand road, not more than 6 feet across. I don't think wave action is responsible for the honeycomb effect. Getting warmer...
UPDATE 07-07: And the answer is...
The little craters are made by tadpoles in the evaporating puddle. The substrate is silty sand. I have no idea why they do this, only to somehow escape into deeper water, but you can see a couple of dead ones that got trapped.
