The video captures an underwater scene with a group of small, colorful fish swimming around a sea urchin on a sandy ocean floor. The fish appear to be feeding or interacting with the sea urchin and some seaweed. The water is clear, allowing for a detailed view of the marine life and the sandy bottom, which has patches of green algae. The overall environment suggests a vibrant and active underwater ecosystem.
A group of variously colored fish, including blue, green, and striped ones, swim around and gather on the sandy ocean floor, which is covered with patches of algae and coral. The fish appear to be interacting with two sea urchins on the seabed, pecking at them and possibly feeding on them. The fish continue to circle and peck at the sea urchins, showing coordinated movement and behavior. The scene remains consistent with the fish maintaining their focus on the sea urchins, occasionally changing their positions and orientations.
