Social groups can moan and bellow at night to each other around breeding areas. Right whales feed mainly on copepods but also consume krill and pteropods. Group size is difficult to determine because of the dispersion. This species is threatened by being separated from calving areas due to shipping traffic by, ship collisions and by becoming tangled in fishing nets, entanglement sometimes causing serious injury or death because fishing gear can wrap around the whale’s mouth and stop it from feeding or cause it to drown because it cannot surface for air. Despite many protections including a moratorium on whaling since 1986, many species of cetaceans continue to be threatened – with some on the verge of extinction. Most live in its western portion, spending most of the year feeding along the coasts of eastern Canada and the northeastern United States. Right whales feed anywhere from the waters surface to the bottom of the water column. These whales are quite social and swim alongside other species of cetaceans. The shift in the availability of food has already damaged the reproductive rates of this endangered whale. And finally, warming oceans have forced copepods, a tiny crustacean that’s the main staple of the North Atlantic right whale’s diet, to migrate north.

The species migrates between two essential habitats: calving grounds and feeding grounds, the latter in the north of the range and the former in the warmer waters of the south of the range, in bays or shallow coastal waters. These whales usually are not afraid of boats and can easily be approached by them. Extensive patches of minute animals and plants that they eat will likely change in abundance or move elsewhere as seawater temperature, ocean currents and winds alter due to climate change.
