Sindya N Bhando, Even Ocean Dwellers Decorate for Company. New York Times, Aug 20, 2013 (in Science Times section).
(entire text: "For years, scientists were baffled by large circular patterns on the ocean floor, with peaks decorated with shell and coral fragments. These 'crop circles' of the ocean floor are created by male puffer fish in order to attract females, researchers report in the journal Nature. The center of the circle serves as a nest where females who find the male and his nest pleasing lay their eggs")
