caption: The image shows a close up of a horseshoe crab on the beach, with its body submerged in the water and its fins and tail visible. Its eyes are wide open, giving it a curious expression, and its mouth is slightly open, as if it is about to take a bite. Its body is a light brown color with white spots, and it has a long, thin snout. Its fins are a darker brown color and its tail is long and thin.
