Are orcas more like us than we ever dared to imagine?
In short: Orcas are apex predators that can reach thirty feet in length, yet they possess a level of intelligence that rivals our own. Scientists have discovered that these social creatures maintain unique family structures, cultures, and dialects passed down through generations, revealing a complex, hidden world beneath the ocean surface.
National Geographic explorer and photographer Brian Skerry has spent over two decades documenting the lives of marine animals, including a recent three-year project focused on the complex world of whales. During his expeditions, Skerry observed orca pods in locations ranging from the waters off Norway to New Zealand. These encounters revealed that orcas, which are actually members of the dolphin family, exhibit behaviors that suggest a sophisticated social intelligence. They are highly tuned acoustic animals, capable of sensing human heartbeats and agitation, which requires divers to remain calm to avoid appearing threatening.
The research suggests that orcas possess distinct cultures and dialects, with behaviors and family structures transmitted across generations. Unlike many other predators, there are no documented instances of orcas killing humans in the wild. Despite their massive size—often described as school bus-sized—they display a curious nature. During one encounter in Norway, Skerry observed an orca calf circle him repeatedly, an interaction he attributed to the animal's likely lack of prior experience with humans underwater.
Skerry’s own path to becoming an underwater explorer began in an unlikely place: the flooded stone quarries of his hometown in Massachusetts. As a young diver, he navigated these dark, deep waters, which were littered with stolen vehicles discarded by others. He eventually turned this hazardous environment into a semi-lucrative endeavor, salvaging parts from submerged cars to sell. This early experience in challenging, deep-water conditions helped prepare him for his later work documenting the mysterious and powerful lives of orcas in the wild, an effort that culminated in the Disney+ original series, The Secrets of the Whales.
