Goose-Beaked Whale Physical Description

The surprising Goose-Beaked Whale attains a size roughly equal to that of other types of beaked whale. No discernible degree of sexual dimorphism has been observed.

Both genders reach an average length of 16 – 23 ft (5 – 7 m). An average weight for both males and females equals roughly 5,500 lb (2,500 kg). However, exceptional individuals have been seen.

The body grows rather robust and somewhat cigar-shaped. Its head remains comparatively short and displays an only slightly defined beak, or rostrum.

Its coloring actually varies significantly among individuals. However, various shades of reddish-brown and dark gray predominate.

In addition, the melon often appears either white or cream-colored.

Goose-Beaked Whale Distribution, Habitat, and Ecology

The fascinating Goos-Beaked Whale possesses a truly cosmopolitan distribution. In the Northern Hemisphere, it inhabits both the North Pacific and North Atlantic.

In the Southern Hemisphere, the creature occurs as far south as Tierra del Fuego, Africa, and Australia. It also has been known to inhabit inland bodies of water, such as the Gulf of Mexico.

While it does occasionally inhabit the shallower regions, such as the Gulf of Mexico, this cetacean typically lives in the deep offshore waters.

The diet of this species remains rather restricted. It feeds primarily on various types of small squid. However, it often supplements this with a variety of small fish.

Amazingly, despite its comparatively small size for a whale, it frequently engages in deep dives. In fact, a tagged individual undertook the deepest known dive by a mammal.

It remained underwater for an astounding 2 hours and 17 minutes. It also reached a depth of 9,816 ft (2,992 m).
