Hector's Beaked Whale - Vacuum of the Sea

Hector's beaked whaleThe Hector's beaked whale (Mesoplodon hectori) is less well known than many of its cetacean cousins, and is a relatively unique specimen within the world of whales and dolphins. While the presence of the beak may draw more comparisons to the latter, genetically and functionally speaking it belongs among the ranks of the former. The Hector's beaked whale is incredibly rare, and thus comparatively little is known about it. However, it stands as one of the ocean's most fascinating creatures.

Physical Characteristics

The smallest of the beaked whales, these oceanic mammals generally come in at around 4.2 meters (13.8 ft), and weigh about 1 tonne, or 2,204 lbs, in size closer to a Bottlenose dolphin than most whale species. Its most prominent physical characteristic is the beak which it shares with other members of its genus.


Generally, the Hector's beaked whale prefers a temperate climate. Many have been recorded around New Zealand, but observations have placed them near Tasmania, South Africa, and the southern tip of South America.


What separates the beaked whales from other cetacean species is their method of consuming their prey. While larger whales have baleen and eat mostly plankton, and killer whales and dolphins use more traditional hunting methods, the beaked whales hunt by suction.
Their primary prey consists of fish and squid hunted in deep water.


Unlike many aquatic species, the Hector's beaked whale is presumed to be safe from extinction, at least for the moment. It has not been observed live in the wild since 2007, and has never been hunted for sport or for food. Many beaked whale species display an above-average sensitivity to aquatic sonar, however, and naval exercises have been known to inflict casualties on other species in the genus. Due to its deep water habitat, the Hector's beaked whale is presumed to be safe from such interference. While numbers of the species are probably somewhat low, this is presumed to be natural, and the species is not marked as endangered.

The Mystery

Little is known about the Hector's beaked whale. Until recently, no specimens had ever been properly described; the only ones recorded were in fact Perrin's beaked whales, a similar species. As such, little is known about how this species breeds, how it behaves socially, and what its challenges are within its environment. Its bizarre capacity for suction remains a fascination for scientists, who hope to unlock its mysteries someday.
