Cuvier’s beaked whales are the deep diving champions of the ocean. Accidents involving boats and commercial fishing account for many injuries and deaths of the Cuvier’s Beaked Whale annually. Life span is uncertain, but probably reaches 60 years. Cuvier’s beaked whales tend to avoid ships and large vessels, reacting when they are still large distances away. A voluntary 50 nautical mile (92.6 km) exclusion zone has now been created around the Canary Islands for naval exercises and no further strandings have occurred in this area. In May 1996, in the waters off Greece, 12 Cuvier’s beaked whales stranded alive and dead along the coast. Cuvier's beaked whales occur year-round off Cape Hatteras, North Carolina, where they occur in very high densities [29–31] and exhibit strong site fidelity [7,32,33]. Due to color variation and scarring no two look exactly alike. However, little is known about the life history of Cuvier’s beaked whales. Distribution. Since they don’t have teeth to grip their prey, Cuvier’s use a suction method to feed; they slurp and suck squid into their mouths! Cuvier’s beaked whales are amazing, but like so many species, they are vulnerable to human activities. They live in deep offshore waters in all oceans of the world except for the Arctic and high latitudes of the Antarctic. The record-breaking longest dive recorded was by a whale that held his or her breath for a phenomenal 222 minutes (3 hours and 42 minutes). Credit: Andrew J. Cuvier’s are one of the best-known beaked whales as they live throughout the world and have been the focus of whale research efforts in areas where deep waters are found close to shore such as Hawaii, the Canary Islands, the Mediterranean and the Bahamas. Dives between 1000m and 2000m deep and lasting over an hour are not unusual for Cuvier’s. An adult female has been identified off the island of Hawaii in eight different years. Registered 501(c)(3) nonprofit organization, Saving the endangered North Atlantic right whale, Meet Delilah – Our Inflatable North Atlantic Right Whale, Sharing the Seas – Safe Boating for Sailors. However, there are cases of Cuvier’s appearing curious around small boats that are motionless in the water. By supporting WDC, you can help Cuvier's beaked whales to live safe and free. Maximum length in males is 32 ft (9.8 m) and in females is 28 ft (8.5 m). These strictly oceanic, deep diving whales have an inconspicuous surfacing behaviour and are hard to observe at sea.

The most commonly observed of this group is the Cuvier’s beaked whale. Cuvier’s have a cone-shaped head, with a stubby beak and two throat grooves. And although details of the reproduction of Cuvier's beaked whales are unknown, they are thought to reproduce at a low rate and females only have a baby every few years. The body is torpedo-shaped and robust; the back and sides are dark grey and the belly and head are much lighter. Cuvier’s beaked whales are the among the most widely distributed of all the beaked whales. Cuvier’s beaked whales, Ziphius cavirostris (G. Cuvier, 1823), aka goose-beaked whales, get their genus name from the Greek word xiphos, which means “sword;” the species name comes from the Latin words cavus and rostrum which mean “hollow” and “beak” respectively. Cuvier’s beaked whales have a robust body. Cuvier’s beaked whales are the most widespread beaked whale. They have the most cosmopolitan range of any of the 21 or so beaked whale species, and can be found nearly anywhere in deep water greater than 200 metres –although they seem to prefer waters with a steep topography over or near the continental shelf. The Cuvier’s beaked whale is one of the larger members of the beaked whale family. Cuvier's beaked whale (Ziphius cavirostris), is the only member of the genus Ziphius.It is the most widely distributed of all the beaked whales..

Following naval exercises, they  have stranded in large numbers in the Canary Islands and off the Bahamas in the North Atlantic, as well as the Mediterranean. Keep up-to-date with all the news from WDC and the world of whales and dolphins. Researchers say they are capable of reaching depths of almost 3,000 metres (1.86 miles). This species holds the mammalian records for the deepest dive (2,992 m 9,816 feet) below the ocean surface, and for the longest dive (222 minutes). An adult female has been identified off the island of Hawaii in eight different years. In older males the head and much of the back is white. Cuvier’s live far out to sea where they make long, deep dives searching for squid during both day and night. However, little is known about the life history of Cuvier’s beaked whales. It is one of the most frequently seen beached whales, despite preferring deep pelagic waters, usually deeper than 1,000 m (3,300 ft). The short mouth-line curves upwards and looks like a smile. Normally Cuvier’s beaked whales are known to avoid boats, but have been known to be quite inquisitive of the ferries passing through the Bay of Biscay. These are caused by surfacing too swiftly, perhaps in response to being frightened and panicked by acute noise. Starting in 1999, dedicated research focused on the following aspects of Cuvier’s beaked whale ecology: a study of the presence and trends in abundance of Cuvier’s beaked whales, as well as sperm whales and Risso’s dolphins, in selected portions (inner and upper continental slope) of the Pelagos Sanctuary, between 1996 and 2000. The Mediterranean subpopulation is listed as Vulnerable. At least four of the whales were found to be bleeding from the eyes. Cuvier's Beaked Whales can be readily identified by their sloping foreheads, short stubby beak, pale head, and the exposed teeth of males. Together, we can: By adopting a whale or dolphin, by making a donation, or by fundraising for WDC, you can help us provide a safe future for these amazing creatures.

Cuvier's beaked whales are described as the 'true megastars' of the diving world. Newborns Cuvier’s beaked whales are 2.7m long and weigh 275kg. The oldest stranded individuals that have been aged have been in their thirties and forties, but it is likely that Cuvier’s can live much longer to around 60 years. Several decades after his death, it was learned that Cuvier's beaked whale was an existing living whale found in the offshore waters of all the world's oceans. They have a distinctive colouration which varies from dark-grey to red-brown, but they have a pale grey melon, light coloured lower jaw and pale patch from the melon to the dorsal fin. They can grow to 7m long, and reach 3tonnes in weight; females are usually heavier than males.

Cuvier’s are hard to find because they live in deep water and spend only short periods at the surface to breathe. Cuvier’s beaked whales or “goose-beaked whales” because of their curved snouts, can dive for incredibly long periods of time to forage for food, avoid predators or to escape the surface world. However, little is known about the life history of Cuvier’s beaked whales. Cuvier's Beaked Whales are widely distributed in tropical to subpolar waters. In 2004, in the Canary Islands, another NATO exercise coincided with a mass stranding of Cuvier’s beaked whales. In May 1996, in the waters off Greece, 12 Cuvier’s beaked whales stranded alive and dead along the coast. These strandings occurred right after NATO exercises involving the use of loud mid-frequency sonar. Although the Cuvier’s Beaked Whale is not often observed out at sea, it seems to be one of the most abundant and widely distributed of all of the beaked whales. Males have only two teeth at the tip of the lower jaw and they often protrude like small tusks in older males.
