The video shows a group of jellyfish swimming in the ocean. The jellyfish are translucent and have a bell-shaped body with tentacles hanging from the edges. They are moving slowly and gracefully through the water. The ocean water is a deep blue color, and the light from above creates a shimmering effect on the jellyfish. There are no other visible creatures or objects in the video, just the jellyfish and the vast expanse of the ocean.
