The video shows a large snake, possibly a boa constrictor, swimming in a body of water. The snake's body is mostly black with some yellow spots. It moves slowly and gracefully through the water, which is clear enough to see the rocks and plants at the bottom. The snake's head is visible above the water, and it appears to be looking around. The word "PANACONDA" is displayed in large, bold, orange letters at the bottom of the screen throughout the video.
