A North Atlantic right whale feeds on the surface of Cape Cod bay off the coast of Massachusetts. That's more born in a single winter since 2016 and it's only about half way through the calving season. The habitat needs of right whales can be inferred from the seasonal distribution of the population and the types of activities observed in the areas that the animals frequent. The alarming results from this research, led by Dr Fredrik Christiansen from Aarhus University in Denmark, were published this week in the journal Marine Ecology Progress Series. Since large-scale commercial whaling stopped in the last century, most populations of southern right whales have recovered well, and now there are about 10,000 - 15,000 right whales in the southern hemisphere.

Unfortunately, the same cannot be said for the North Atlantic right whales, found today off the east coast of North America. North Atlantic right whales, Eubalaena glacialis, earned their common name because of the ease with which they were hunted – they were literally the 'right' whales to hunt.Right whales are bountiful in blubber, giving them exceptional buoyancy, even after death. Once common along the eastern U.S. seaboard, the whale was hunted to near-extinction by the 1750s. Population of North Atlantic right whales dips again, to 366. We used an abundance estimation model to derive estimates of cryptic mortality for North Atlantic right whales and found that observed carcasses accounted for only 36% of all estimated death during 1990–2017.

The right whale was considered a single species and designated Endangered in 1980. Fewer than 250 mature individuals were estimated to be alive at the end of 2018, the total population having declined by approximately 15% since 2011.

These whales were hunted nearly to extinction by commercial whalers by the end of the 1700s, but today are at risk from entanglement in fishing gear and boat strikes.
