The video shows a large hammerhead shark swimming in the ocean. The shark has a distinctive hammer-shaped head and a long, pointed snout. Its body is grey with white underbelly, and it has a long, slender tail. The shark is seen swimming gracefully through the water, with its fins and tail moving smoothly. The ocean water is a clear blue, and the sandy ocean floor is visible below. There are no other creatures or objects in the video, just the shark in its natural habitat.
