Hector's beaked whale is a small toothed whale recorded offshore in cool-temperate waters of the Southern Hemisphere. The sexes differ in color, and species-specific ecological records are limited.
Males are dark gray with a lighter underside; females are generally paler gray and may have white areas. The dorsal fin is small and rounded, and the flukes are broad and straight.
It has been recorded offshore in cool-temperate parts of the Southern Hemisphere, but detailed information on its own diet and behavior is limited.
