The video shows a cuttlefish swimming in an aquarium. The cuttlefish is predominantly dark in color with a slightly lighter underside. It has several tentacles that are curled and extended, and its eyes are large and prominent. The background is a deep blue, suggesting an underwater environment, with some greenish hues that might be from lighting or plants. The cuttlefish moves gracefully through the water, adjusting its fins and tentacles as it swims. The overall scene is serene and captures the elegant movement of the cuttlefish.
