The video shows a large snake swimming in murky green water. The snake's body is dark with black spots, and it has a long, slender shape. The snake moves slowly and gracefully through the water, its body undulating with each movement. The water is filled with green algae, which covers the bottom of the water body. The snake's head is visible, and it appears to be looking around as it swims. There are no other visible creatures or objects in the water. The video is shot from a close-up angle, focusing on the snake's body and head as it moves through the water.
