The video shows a large hammerhead shark swimming in the ocean. The shark is seen from various angles as it moves through the water. The ocean is a deep blue color, and the sandy bottom is visible in some shots. The shark's distinctive hammer-shaped head and long, pointed snout are clearly visible. There are also small fish swimming around the shark, but they do not interact with it. The shark's movements are slow and graceful, and it appears to be calmly exploring its surroundings.
