In the video, a man is seen scuba diving underwater. He is wearing a black wetsuit and a diving mask. The man is holding a blue bucket in his hand, and he is using it to collect water from a large sea star that is sitting on the ocean floor. The sea star is brown in color and has many spikes on its body. The man carefully scoops water from the sea star and pours it into the bucket. The water is clear and the ocean floor is visible in the background. The man seems to be collecting the water for some purpose, but it is not clear from the video what that purpose is.
