Shallow water reveals sandy sea bottom with seaweed and shells.
A shallow area of water is seen from an above angle. The water shows a sandy floor below with brown chunks of caulacanthus seaweed. The several seaweed groups range in size. A large chunk of long green seaweed is seen in the upper right corner of the image below the water's surface as well. The sandy sea bottom also shows white seashells. The water is very shallow and just barely covers the seaweed chunks. The surface is seen from an angle at the upper edge of the image, reflecting the soft blue sky. The floor is covered in rippling caustic lines from the bright sun shining through the water. The caustic lines make the image look like a pointillism painting. The sun shines from the left, and small shadows are seen on the right.
