The video shows a person's finger pointing at a worm-like creature on the sandy bottom of a body of water. The creature is long and slender, with a smooth, shiny surface. It moves slowly and gracefully, undulating its body as it moves. The person's finger follows the creature's movements, pointing at it as it moves. The water is clear, and the sandy bottom is visible, with small rocks and pebbles scattered around. The creature's color is a pale, translucent white, and it stands out against the darker sand. The video captures the creature's movements in detail, showing how it contracts and expands as it moves.
