The video shows a seal swimming underwater. The seal is seen swimming near the surface of the water, with its head and flippers visible. The water is clear, and the seal is surrounded by rocks and other marine life. The seal appears to be moving gracefully through the water, occasionally turning its head to look around. The light from the surface of the water creates a beautiful effect on the seal's body, highlighting its sleek and smooth skin. The seal's movements are slow and deliberate, and it seems to be enjoying its time in the water.
