The video shows a sea slug, specifically a nudibranch, moving slowly across a sandy ocean floor. The nudibranch has a distinctive pattern with white and reddish-brown colors and small appendages on its back. It glides gracefully over the sand, leaving a slight trail behind it as it moves. The background is a uniform sandy surface, indicating a relatively calm underwater environment.
A sea creature with a textured, brown and white body is seen on a sandy seabed. The creature has two prominent brown spots on its head and a small, fin-like structure at the back. It begins to move slowly forward, maintaining a straight line on the sand. The background remains consistent, showing a uniform sandy seabed with no other visible objects or creatures.
