This media file shows a large school of fish swimming in the ocean. The fish are silver and blue and appear to be trevally, a type of jack. They are swimming in a dense school, which is a common behavior for these fish, offering protection from predators. The water is clear and blue, suggesting a tropical or subtropical environment. There are no people or man-made objects visible in the media. The schooling behavior indicates a natural event, likely occurring during daylight hours when visibility is good for hunting and predator avoidance. The sheer number of fish in the school is a notable detail, creating a visually impressive spectacle. There is no visible text in the media file. Given the context of Hamburg, Germany, it is important to note that this underwater scene is not representative of Hamburg's local environment. The fish and oceanic setting are indicative of a distant marine location, not the Baltic Sea or North Sea accessible from Hamburg.
