On land, humans like to think they sit comfortably at the top of the food chain. We walk upright, see clearly, move fast enough, and understand our surroundings. The moment that environment shifts from dry ground to open water, that confidence collapses. Without boats, engines, or protective barriers, people become slow, awkward, and poorly adapted to the underwater world. Vision is limited, movement is restricted, and awareness drops fast. In that environment, humans are no longer dominant hunters but potential prey.
