Razorfish, Papua New Guinea - Around coral reefs in the South Pacific and Indian Oceans, divers may come across schools of razorfish, swimming nose-down in the current. Why do these small fish swim in this position? It’s a form of camouflage. Aside from finning about coral reefs in a pose that doesn’t make them immediately look like fish, razorfish can also easily hide in the spines of a nearby sea urchin. So they’re more likely to be passed by when predators swim past, looking for a meal.
