caption: The image shows a horseshoe crab on the beach, its body glistening in the sun as it moves across the sand. Its long, slender body is a deep brown color, and its wings are spread wide as if it is ready to take flight. Its antennae are long and thin, and it has a large, round head with two large eyes. Its legs are thin and spindly, and the sand around it is a light tan color.
