North Atlantic right whales are baleen whales that feed entirely on zooplankton and their favourite types are large copepods which are about the size of a grain of rice. Oceans warming up can impact the food sources of whales. North Atlantic right whales can live up to 70 years. They migrate from a calving ground near Florida and Georgia on North America's eastern seaboard, to summering grounds in the Bay of Fundy, the Gulf of Maine, and the Scotian Shelf, with some animals going as far as the Gulf of St Lawrence, the Denmark and Davis Straits and sometimes Iceland and Norway. They filter out these tiny organisms from the water through their baleen, where the copepods become trapped in a tangle of hair-like material that acts like a sieve. By Doug Fraser. During the first year the calf learns from its mother where the critical feeding grounds are, and it will visit them for the rest of its life. Bio-energetic studies suggest that right whales require between 407,000 and 4,140,000 calories per day – the equivalent of between 0.25 and 2.6 billion C. finmarchicus C5 at an estimated energy content of 6.78 J per individual ( Kenney et al., 1986 ). North Atlantic right whales are highly specialized planktonic feeders, and a decline in the availability of these microscopic marine creatures in the areas where the whales occur means they are short of food. Hundreds of years of commercial whaling decimated the species by the early 1900s. Right whales feed by opening their mouths while swimming slowly through large patches of minute zooplankton and copepods. They will often be found skim feeding at the surface of the water on dense patches of copepods (plankton), but can feed at deeper depths in the water column.

Currently this species is classified as Endangered (EN). The species got its name as the “right” whale to hunt: these animals swim slowly close to shore and are so blubber-rich they float when dead. Their scientific name, Eubalaena glacialis, means “good”, or “true whale of ice.” Eubalaena is derived … According to the IUCN Red List, the total population size of the North Atlantic right whale is estimated to be around 300-350 individuals.

Northern right whales tend to move through the ocean at a fairly slow pace for an animal of their size, they feed near the surface, and they float when killed; thus they were considered the "right" catch for whalers. Because of their docile nature, their slow surface-skimming feeding behaviors, their tendencies to stay close to the coast, and their high blubber content (which makes them float when they are killed, and which produced high yields of whale oil), right whales were once a p… No aggression is seen between competing males, a rare behavior for mammals. During feeding seasonthese whales may be seen gathered together in areas that are highly concentrated with krill and various invertebrate that they can feed on.

North Atlantic right whales are sexually mature between 8 – 11 years old. Like other baleens, these whales use filter feeding for capturing their prey. Right whales feed mainly on copepods but also consume krill and pteropods. How can such a huge mammal simply disappear within reach of the richest and most powerful nation on earth? Humans are killing the endangered North Atlantic right whale far faster than previously thought, and experts say the window to act is quickly closing. White calluses on its head are actually whale lice buried in the skin. Right Whale Diet The Right Whales diet consists primarily of zooplankton and tiny crustaceans such as copepods, as well as krill and pteropods, although they are occasionally opportunistic feeders. Learn more about whales and dolphins and what we can do to protect them. Feeding Right whales primarily feed during the spring and summer months in higher latitudes. North Pacific right whales prefer large calanoid copepods—are crustaceans about the size of a grain of rice—but they will also eat krill and larval barnacles. The North Atlantic right whale (E. glacialis) inhabits the chilly waters of the northern Atlantic ocean. A pair of blowholes on its head cause the right whale's spout to have a distinctive V-shape. 3. North Atlantic right whales are one of the most endangered large whale species in the world.

Diet: Plankton; Status: Critically endangered; Distribution: North Atlantic Right Whale Range Additional Content. This forces the whales, which must eat about 2,000 pounds of food daily, to travel outside of protected areas to feed, making them more vulnerable to vessel strikes and gear entanglement. It is a big, mostly black animal with some whitish patches on its head and belly, it lacks a dorsal fin, and it has a graceful, deeply notched tail or "fluke".

Hunting of right whales began as early as the 10th century. The underlying cause is probably their diet. As with other species of baleen whalethese whales use a hunting method known as filter feeding to capture their prey. The North Atlantic right whale (Eubalaena glacialis, which means "good, or true, whale of the ice") is a baleen whale, one of three right whale species belonging to the genus Eubalaena, all of which were formerly classified as a single species.

The usual group size ranges from two to 12 but is usually two. They form a distinctive pattern … 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.
