Scientific understanding of narwhals developed gradually over centuries, constrained by the extreme remoteness and ice-covered habitat of the Arctic whales. Early European knowledge of narwhals came almost entirely through trade in their distinctive tusks, which were long believed to be the horns of unicorns and commanded high prices as rare curiosities. Only as naturalists began serious study did they recognize these tusks as teeth and identify narwhals as Arctic cetaceans with unique anatomy adapted to their polar environment.

Indigenous Inuit hunters accumulated the earliest reliable knowledge of narwhal behaviour, migration patterns, and ecology through generations of direct observation and interaction with the species. Their expertise provided a foundation upon which scientific inquiry would later build. The transition to modern research accelerated significantly with the advent of new technologies. Satellite tagging, acoustic recording equipment, and aerial survey methods enabled researchers to track narwhal movements across vast distances, document their deep-diving capabilities, and map population structure in previously inaccessible regions.

Contemporary narwhal science has expanded to include genetic analysis, revealing unexpected connections between populations and even instances of hybridisation with beluga whales. These studies have transformed understanding of narwhal biology, behaviour, and population dynamics in ways impossible through earlier observation alone. Today, the most effective narwhal research integrates advanced technological tools with the accumulated wisdom and observations of Indigenous communities, demonstrating that scientific progress in Arctic marine biology depends on combining modern methods with traditional knowledge systems.
