Crater like structures created by a unique crab species

At first look, these photos look like of dry land craters photographed from airplanes or satellites. But unbelievably, these perfectly round shapes are created on seashore sand by a unique species of crabs. Fate was bad that I could not photograph the crabs, but their creation was amazing to paint on pixels.



We were in Konkan [a portion of the UNESCO declared World Heritage Site of Western Ghats] a couple of years back, in winter. The less popular coastline of Konkan is very beautiful and full of surprises. One of those surprises was the collection of these masterpieces all over the shoresand. At first, we were in awe and confusion as to how these must have been created. Then we found some tiny crabs coming out of them. They were just a couple of centimeters in size. Just as they came out, they ran straight towards sea leaving behind for us their artwork to photograph.
