North Atlantic right whale skeleton found on the Thames in 2010 at Bay Wharf, Greenwich. The whale's scientific name is Eubalaena glacialis, which means "good, or true, whale of the ice". The cladogram is a tool for visualizing and comparing the evolutionary relationships between taxa. The point where a node branches off is analogous to an ...
Almost all of the 400 North Atlantic right whales live in the western North Atlantic Ocean. In northern spring, summer and autumn, they feed in areas off the Canadian and northeast U.S. coasts in a range stretching from New York to Newfoundland. Particularly popular feeding areas are the Bay of Fundy and Cape Cod Bay.
At least 15,000 whales are estimated to inhabit the North Atlantic. [35] In the Northeast Atlantic, two orca ecotypes have been proposed. [36] Type 1 orcas consist of seven haplotypes and include herring-eating orcas of Norway and Iceland and mackerel-eating orcas of the North Sea, [36] as well as seal-eating orcas off Norway.
The remote Portuguese archipelago, consisting of nine volcanic islands about 900 miles west of Lisbon, lies in the North Atlantic Ocean, putting it on the migration route of several whale species ...
In the North Atlantic, 12,000 whales were estimated. As of 1983, around 10,000 whales were estimated in the Southern Hemisphere, and by 2011, approximately 35,000 individuals inhabited the North Pacific. [2] Sei whales were said to have been scarce in the 1960s and early 1970s off northern Norway.
Though some whale migration routes are known to exceed 8,000km between feeding and breeding grounds, such long-distance movement between longitudes is “atypical”, scientists say.
A whale nicknamed 'Black Heart' was the first sighted in the Southern U.S. for the 2024-25 calving season. The female, around 19 years old, was spotted off the North Carolina coast in November.
The northern Pacific and Atlantic populations are also distinct, with the North Pacific right whale being more closely related to the southern right whale than to the North Atlantic right whale. [9] Genetic differences between E. japonica (North Pacific) and E. australis (South Pacific) are much smaller than other baleen whales represent among ...
