The video captures a dark-furred animal, likely a rat or a nutria, swimming or floating in dark, murky water. The animal's head, which is dark brown or black, is visible above the water surface, with its snout and eyes distinguishable. A long, thin tail is partially submerged and visible extending behind it. The water surface is covered with scattered white foam bubbles and small pieces of debris, including a few green leaves and reddish-brown fragments. The water appears calm and still. The scene is consistent with an urban waterway.
