Brain coral Jan 29, 2022

Brain coral

By using a long exposure and rotating the camera, a photographer highlights the spherical shape and grooved surface of a brain coral. You needn"t be a genius to guess how brain coral got its name. But you could just as easily call it "maze coral" after its labyrinthine surface. Either way, this sea organism is an apt mascot for today"s cerebral celebration: Puzzle Day!
