The white-beaked dolphin (Lagenorhynchus albirostris) is a marine mammal belonging to the family Delphinidae (oceanic dolphins) in the suborder Odontoceti (toothed whales). A new study gives a first look at the presence and potential effects of these pollutants in stranded dolphins and whales along the coast of the ... white-beaked dolphin and Gervais' beaked whales. Sensitive beaked whales are well-adapted to be deep divers. Cuvier’s sometimes raise their tail flukes above the water which helps them dive steeply down. An adult female has been identified off the island of Hawaii in eight different years. Trues Beaked Whales Pygmy Sperm Whales. Dolphin Physical Characteristics Colour. By supporting WDC, you can help Baird's beaked whales to live safe and free. Baird's beaked whales can tuck their flippers away into small depressions in their sides when they want to dive. Physical Description: This large stocky animal resembles a cross between a bottlenose whale and a typical beaked whale. large size and coloration of Baird’s beaked whales is comparable with minke whales, but Baird’s beaked whales have a pointed beak, no baleen, and are typically found in groups. They are especially vulnerable to intense noise created by military sonar. The Cuvier's beaked whale is the deepest diving mammal, having reached the amazing depth of 2992 metres. They have a small dorsal fin positioned two-thirds of the way back on the body. False Killer Whales. Ocean noise is a big threat to these deep diving specialists. The Cuvier’s beaked whale is one of the larger members of the beaked whale family. The body is torpedo-shaped and robust; the back and sides are dark grey and the belly and head are much lighter. Cuvier’s are hard to find because they live in deep water and spend only short periods at the surface to breathe. Baird’s beaked whales actually resemble massive bottlenose dolphins. Cetaceans like dolphins and whales sleep in a pattern called cat-napping. Until recently they were known from only three specimens, all caught incidentally in fishing lines in the Sea of Japan in 1963. However, life amongst the ranks isn’t always so harmonious for these whales, and males in particular can be covered in white scarring from past disputes. They live in deep offshore waters in all oceans of the world except for the Arctic and high latitudes of the Antarctic. There is little information on the social structure of this species, but separation by age and sex may occur. The animals were mostly bottlenose dolphins, although 10 other species were also represented. Denizens of deep, remote ocean waters and highly resistant to life in captivity, they have proven notoriously difficult for humans to observe. They have been observed singly, in pairs, and in small groups. Other names: Northern four-toothed whale; Giant bottle-nosed whale; North Pacific bottlenose whale. Cuvier's beaked whale or the goose-beaked whale (Ziphius cavirostris), the only member of the genus Ziphius, is the most widely distributed of all the beaked whales. Dolphins are another matter. And these animals are a lot more deep-diving, smaller whales, so they're not seen as often. This time, we had our cameras ready but got only a glimpse of the whale’s back before it dived. For example they may be found swimming in deeper waters in areas where there have been significant changes to land mass and in situations where food such as herring migrates to another area of the ocean. By supporting WDC, you can help Cuvier's beaked whales to live safe and free. SC040231, Bottlenose dolphin - Charlie Phillips/WDC, Humpback whale underwater - Vanessa Mignon. 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. Based on the location and time, we think it unlikely that this was the same individual that we had seen an hour earlier. Beaked whales are toothed whales and found in waters deeper than 200 m and near continental shelf areas. White-beaked dolphins are very curious and often swim in the bow waves alongside fast ships and boats, thus, common companions of whale watchers in Faxaflói bay. The sounds are made by squeezing air through nasal passages near the blowhole. In the Bahamas, it took 15 years to gather enough data to note a decline in beaked whale abundance on a military testing range (Claridge, 2013). Tours . Beaked whales are one of the most elusive, least known group of cetaceans (whales, dolphins and porpoises) but they are all-round awe-inspiring. A dead Cuvier's beaked whale washed up on the Porirua coast in 2014 – its body weighed about 2 tonnes. Beaked whales are kind of similar looking to dolphins - they have kind of that long rostrum look to them.
Unlike the short-beaked common dolphin that tends to prefer oceanic waters, the long-beaked form seems to favour shallower, warmer waters and generally lives closer to shore.Long-beaked common dolphins have possibly the highest tooth-count of all dolphins with between 47 – 58 sharp, pointed teeth in each row.By supporting WDC, you can help long-beaked common dolphins to live safe … Females don’t have any visible teeth.

Although we know a bit about their migratory movements, we still don’t know for certain where Baird's beaked whales go in the winter months. The longest time period for a beaked whale living in captivity was 25 days. A lack of longitudinal data and studies gathering baseline data before the onset of sound-producing events are common problems with cetacean research. ''Beaked whales can suck in their food without need for teeth – rather like we can suck in spaghetti.'' Beaked whales are members of the family Ziphiidae, the second largest family of cetaceans - which includes whales, dolphins and porpoises. Species of Cetacea around the Tristan da Cunha Islands.

Little is known about this family of cetaceans ; one species was first described in 1995, two others are known only from skeletal remains, and the bodies of undescribed species occasionally drift ashore. The Odontocetes, or toothed whales, use teeth to seize and capture their prey. Short-beaked common dolphins were once actually common in the Mediterranean, but are now very rare. Differing from other beaked whales in size, Baird's beaked whales also have different dorsal fins. Baleen whales, on the other hand, a group to which all big whales except the sperm whale belong, strand very rarely. Dolphins and whales establish strong social bonds through their advanced communication abilities. They also have ‘scars’ from their rather active lifestyle. Study around Bairds beaked whales has led to many questions surrounding their genetic link to other whales. At least four of the whales were found to be bleeding from the eyes. Although both the male and female have rows of tiny teeth in the upper jaw behind the main teeth, males have two small teeth set back from the tip of the beak, which can be seen when the mouth is closed.
