Mesoplodon hectori is a small and rarely observed beaked whale. It differs from Andrews’ beaked whale through its shorter beak and adult male teeth positioned near the jaw tip. It has a compact body, small flippers and a triangular dorsal fin. Adult males may show a pale beak and extensive linear scars.
It is recorded from temperate Southern Hemisphere waters, including New Zealand. Its distribution at sea is inferred largely from stranded animals. Direct observations of feeding and social behaviour are extremely limited. It is presumed to dive for squid and small fish.
The New Zealand classification is Data Deficient. There is no dependable viewing site; occasional strandings have occurred on New Zealand coasts.
