The video shows a manatee swimming in an aquarium. The manatee is a large, gray animal with a flat body and a long, flexible snout. It is swimming in clear water, surrounded by rocks and other aquatic plants. The manatee moves slowly and gracefully through the water, occasionally turning its body or flicking its tail. The aquarium is well-lit, and the water is clean and clear, allowing for a good view of the manatee. The manatee appears to be healthy and comfortable in its environment.
