In the video, a person is seen standing in a shallow body of water, surrounded by rocks and seaweed. The person is wearing a black shoe and is holding a flashlight in their hand. They are reaching into the water and picking up a crab. The crab is brown and has long claws. The person then places the crab back into the water, and it swims away. The water is clear, and the crab's movements are visible. The person's actions are deliberate and careful, ensuring that the crab is not harmed. The surrounding environment is dark, with only the flashlight illuminating the area.
