The video shows a sea slug, also known as a nudibranch, crawling on a bed of green algae. The nudibranch has a white body with black spots and a yellowish-orange border along its mantle. It moves slowly, using its foot to glide over the surface of the algae. The surrounding environment is rich in marine vegetation, creating a vibrant underwater scene.
