In an underwater environment with a blue background, rocks, and aquatic plants, a horseshoe crab is seen on a sandy substrate. The crab begins to move slowly towards the left side of the frame, gradually approaching a round stone. As it continues its movement, the crab's body lowers closer to the sand, and it eventually reaches the stone. The crab's tail extends behind it as it comes to a stop near the stone, resting on the sand.
