Beaked whales enter stealth mode 2011-07-25T04:01:12Z This species was the most commonly beached beaked whale around the New Zealand coast at the time. World's rarest whale seen for first time: Spade-toothed whale 2012-11-05T21:45:00.517Z Sonar drives beaked whales long distances from their favorite deep-water habitats, according to the first study conducted during actual U.S. Navy Sonar May Mimic Killer Whale Sounds 2011-03-18T21:42:55Z Beaked whale species are difficult to identify at sea, but it is likely that this was a Cuvier's beaked whale, one of the most widely distributed members of this family. Scientist at Work Blog: Where the Beaked Whales Are 2012-08-17T19:04:05Z The following four sections summarize characters of western North Atlantic beaked whales. Whales, Dolphins, and Porpoises of the Western North Atlantic A Guide to Their Identification Using suction cups, the researchers attached electronic listening devices to eight Blainville's beaked whales, recording them for 102 hours in total. Beaked whales enter stealth mode 2011-07-25T04:01:12Z Credit: New Zealand Government During the 1950s, a second beaked whale specimen was collected on New Zealand’s White Island and stored in the MacGregor Collection of the University of Auckland. World's rarest whale seen for first time: Spade-toothed whale 2012-11-05T21:45:00.517Z And yet, beaked whales often turn up stranded shortly after the intense sonar exercises the Navy uses to train sailors to detect silent enemy submarines. Navy Sonar May Mimic Killer Whale Sounds 2011-03-18T21:42:55Z This, with the frequent presence of rudimentary teeth in other species of this genus, indicates that the beaked whales are derived from ancestral forms with teeth of normal character in both jaws. Encyclopaedia Britannica, 11th Edition, Volume 5, Slice 7 "Cerargyrite" to "Charing Cross" Figure 77.—Various views of a herd of five or six unidentified beaked whales, possibly dense-beaked whales, 12 miles off Pokai Bay, Oahu, Hawaii. Whales, Dolphins, and Porpoises of the Western North Atlantic A Guide to Their Identification The results, published in the journal Marine Mammal Science, revealed that Blainville's beaked whales fell silent once they entered waters that are shallower than 170m. Beaked whales enter stealth mode 2011-07-25T04:01:12Z Thanks to the discovery, New Zealand gained the reputation of being the richest region in the world for beaked whale species diversity. World's rarest whale seen for first time: Spade-toothed whale 2012-11-05T21:45:00.517Z On this latter view we may regard the tusks of the male babirusa as examples of redundant development, analogous to that of the single pair of lower teeth in some of the beaked whales. Encyclopaedia Britannica, 11th Edition, Volume 3, Part 1, Slice 1 "Austria, Lower" to "Bacon" The smallest sort is the beaked whale, which is about 25 feet long. Old Jack North Sea beaked whales are known to feed on squid. Whales, Dolphins, and Porpoises of the Western North Atlantic A Guide to Their Identification By swimming in stealth mode, the beaked whales avoid broadcasting their location to orcas. Beaked whales enter stealth mode 2011-07-25T04:01:12Z North Sea beaked whales are the most northerly species of beaked whales. Whales, Dolphins, and Porpoises of the Western North Atlantic A Guide to Their Identification The teeth of North Sea beaked whales are located about midway between the tip of the snout and the corner of the mouth. Whales, Dolphins, and Porpoises of the Western North Atlantic A Guide to Their Identification Sea beaked whales are the most northerly of the beaked whale species, extending north as far as the pack ice. Whales, Dolphins, and Porpoises of the Western North Atlantic A Guide to Their Identification Like other members of the beaked whale family, goosebeaked whales lack a distinctive notch in the rear margin of the flukes. Whales, Dolphins, and Porpoises of the Western North Atlantic A Guide to Their Identification Closer examination should permit easy separation, however, since the pygmy sperm whale has a blunted head, while the beaked whales, as the name implies, have elongated "dolphinlike" beaks and are considerably larger. Whales, Dolphins, and Porpoises of the Western North Atlantic A Guide to Their Identification Adult North Sea beaked whales are dark charcoal gray on the back with white spots overall. Whales, Dolphins, and Porpoises of the Western North Atlantic A Guide to Their Identification Throat grooves are short grooves found on the throat of beaked whales, sperm whales, and dwarf sperm whales. Whales, Dolphins, and Porpoises of the Western North Atlantic A Guide to Their Identification True's beaked whales are dull black to dark gray on the back, lighter slate gray on the sides, and white on the belly. Whales, Dolphins, and Porpoises of the Western North Atlantic A Guide to Their Identification Note also the mouth cleft, shorter in this species than in any other beaked whale species, and the slightly concave appearance to the upper margin of the head. Whales, Dolphins, and Porpoises of the Western North Atlantic A Guide to Their Identification True's beaked whales appear to be primarily temperate in distribution. Whales, Dolphins, and Porpoises of the Western North Atlantic A Guide to Their Identification The cleft of the mouth is small, smaller than in any other species of beaked whales. Whales, Dolphins, and Porpoises of the Western North Atlantic A Guide to Their Identification The fact that goosebeaked whales strand more frequently than other beaked whales may reflect either a greater abundance or a greater tendency to approach close to shore. Whales, Dolphins, and Porpoises of the Western North Atlantic A Guide to Their Identification Antillean beaked whales are probably primarily oceanic in distribution and are known to feed on squid. Whales, Dolphins, and Porpoises of the Western North Atlantic A Guide to Their Identification So little is known of the external appearance and behavior of the living beaked whales at sea that all the species may easily be confused. Whales, Dolphins, and Porpoises of the Western North Atlantic A Guide to Their Identification Figure 82.—Two views of an Antillean beaked whale stranded in Jamaica. Whales, Dolphins, and Porpoises of the Western North Atlantic A Guide to Their Identification The range of True's beaked whales overlaps with that of the Antillean beaked whale but is more northerly. Whales, Dolphins, and Porpoises of the Western North Atlantic A Guide to Their Identification The blow of beaked whales is usually small and inconspicuous and reportedly projects markedly forward from the head. Whales, Dolphins, and Porpoises of the Western North Atlantic A Guide to Their Identification If there is no adult male in the group, however, dense-beaked whales may be confused with any of the other beaked whales species. Whales, Dolphins, and Porpoises of the Western North Atlantic A Guide to Their Identification As with other species of beaked whales seldom encountered or at least seldom positively identified at sea, the distribution of goosebeaked whales is poorly known and must be constructed from records of stranded specimens. Whales, Dolphins, and Porpoises of the Western North Atlantic A Guide to Their Identification Both these other species reach substantially greater maximum lengths than True's beaked whales, however, and should be readily distinguishable by this and the number of other highly distinctive characteristics of each species. Whales, Dolphins, and Porpoises of the Western North Atlantic A Guide to Their Identification Antillean beaked whales have been reported stranded from the latitude of Long Island, N.Y. south to Florida, thence into the Caribbean and the Gulf of Mexico. Whales, Dolphins, and Porpoises of the Western North Atlantic A Guide to Their Identification Figure 79.—Two views of the body of a stranded True's beaked whale from northeastern Florida. Whales, Dolphins, and Porpoises of the Western North Atlantic A Guide to Their Identification The photo on the right shows the two V-shaped throat grooves characteristic of beaked whales. Whales, Dolphins, and Porpoises of the Western North Atlantic A Guide to Their Identification North Sea beaked whales have been reported in the offshore waters from the latitude of New England north perhaps to the pack ice. Whales, Dolphins, and Porpoises of the Western North Atlantic A Guide to Their Identification Adult male dense-beaked whales can be separated from the other beaked whales by the high, arching contour to the corners of the mouth. Whales, Dolphins, and Porpoises of the Western North Atlantic A Guide to Their Identification Within their range, they may be confused at a distance with minke whales, with sperm whales, or perhaps with North Sea beaked whales. Whales, Dolphins, and Porpoises of the Western North Atlantic A Guide to Their Identification Antillean beaked whales are dark grayish black on the back and sides, slightly lighter on the abdomen. Whales, Dolphins, and Porpoises of the Western North Atlantic A Guide to Their Identification Compared to the smaller True's beaked whale, Antillean beaked whales have a smaller head, a narrower beak, and a taller, narrower body.
