White-beaked dolphins are not fussy eaters. These energetic dolphins are solidly built and stockier than other species of dolphins, a characteristic of smaller whales that have adapted to colder habitats. "White-beaked dolphin Lagenorhynchus albirostris Gray, 1846." It is estimated that around 30,000 white-beaked dolphins inhabit the coasts of Iceland, with an estimated worldwide population of 100,000 animals. The dolphin generally feeds on various small fish, such as mackerel and herring, or squid. Based on recent surveys, our scientists estimate that there are about 2,000 dolphins in this stock. Diet: White-beaked dolphins are known to feed on a variety of both schooling and bottom-dwelling fish (herring, capelin, cod, haddock and whiting), invertebrates (squid and octopus), and benthic crustaceans (2, 10). 1984. At the population level, there is currently no evidence to support that the Gulf of St. Lawrence harbors a resident, genetically distinct population of white-beaked dolphins, and molecular and morphological studies are ongoing to investigate population structure of this species across the North Atlantic (6-8). The white-beaked dolphin, like all dolphins, belongs to the toothed whales.

Report for Hydro-Québec, Vice Présidence Environment. The whistle of white-beaked dolphins reaches a significantly higher frequency than is known among other dolphin species. Little is known about the white-beaked dolphin’s life expectancy, but the oldest found was 47 years, and they are therefore estimated to reach an age of 50 years. White-beaked dolphins are highly susceptible to changes in sea temperature. The white-beaked dolphin is currently one of six species grouped together within the genus Lagenorhynchus; however, data based on molecular genetics suggests that the six members of this genus are not closely related and should be split up into multiple different genera (e.g., 3, 4). (8) Fernández R, Schubert M, Vargas-Velázquez AM, Brownlow A, Víkingsson GA, Siebert U, Jensen LF, Øien N, Wall D, Rogan E, Mikkelsen B, Dabin W, Alfarhan AH, Alquraishi SA, Al-Rasheid KA, Guillot G, Orlando L. 2016. 27 In contrast, to date, morbilliviruses have been observed as incidental pathogens in 3 species: harbor porpoises (Phocoena phocoena), 18 white-beaked dolphins, 24,34 and a pygmy sperm whale (Kogia breviceps). It is thought their range may contract significantly with any rises in sea temperature as a result of climate change.

The population, breeding pattern, and life expectancy of the dolphin are all unknown, although most sources estimate several hundred thousand individuals, more densely populated in the eastern North Atlantic than the west.

White-beaked dolphins are a subpolar species, common in the cooler waters of the North Atlantic. +(354) 497 0000 White-beaked dolphins are the loudest at the surface while feeding but rather quiet while travelling or resting.

White-sided dolphins can swim in very tight formations, practically touching one another. Downloaded on 29 February 2016. White-beaked dolphins use a variety of whistles to communicate. They are one of the most commonly sighted whale species in Faxaflói bay. 5.

White-beaked dolphins are not considered an endangered species. White-beaked dolphins are fast, powerful swimmers. (4) McGowen MR. 2011. Mol Phylogenet Evol 60: 345-357. They also like to feast on squid and various crustaceans. To manage white-beaked dolphins in U.S. waters, we have placed them into a western North Atlantic stock. Behind-the-Scenes Virtual Expedition: White Sharks and Whales. Phylogeography and population dynamics of the white-sided dolphin (Lagenorhynchus acutus) in the North Atlantic. Individuals whose stomach contents were analysed in the Netherlands were found to have over 25 different species in their bellies.

Conservation: According to the International Union for Conservation of Nature and Natural Resources (IUCN), the white-beaked dolphin is considered Least Concern (9). The dorsal fin of a white-beaked dolphin is larger than you might expect and the flippers are broad and pointed and almost 20% of the total body length! White-beaked dolphins are most often seen in smaller groups, although occasionally several groups will merge into larger pods with over 1,500 animals.
