Sharks or dolphins, two predators, two different morphological responses to the same environmental constraints. Who is best suited to survive? An underwater camera flies over a coral sandbar then stops to discover a black and white image of a razorfish lurking in the relief. Several bottlenose dolphins feed here. Mothers spot razorfish with their sense of echolocation, and teach their young to master this sophisticated sense that we have no idea. Other bottlenose dolphins have developed another spectacular application of this sense and hunt in the muddy waters of the mangroves the mules that they wash up on the banks. Other applications of this natural sonar by another species of dolphins: descend in groups into the abyss to spot schools of anchovies and bring them up to a shallower depth where they will be stuck on the natural barrier that is the surface. But how to hunt in the dark of the abyss when you don't have this sonar? Sharks have senses capable of detecting vibrations or weak electric fields... But by the way, dolphin or shark face to face, which is stronger? Can a shark resist an orca? The black and white dolphin has such an arsenal of senses, such a hunting culture transmitted from one generation to another, such adaptability to changing environmental conditions that the animal today dominates all the oceans of the world.
