It is hard to guess what a North Atlantic right whale weights. But we have the answer:
An adult North Atlantic right whale (Eubalaena glacialis) on average weights 23000 kg (50706.26 lbs).
The North Atlantic right whale is from the family Balaenidae (genus: Eubalaena). It is usually born with about 800 kg (1763.7 lbs). When reaching adult age, they grow up to 13.92 meter (45′ 9″). Usually, North Atlantic right whales have 1 babies per litter.
As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.
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. 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 preferred target for whalers.At present, they are among the most endangered whales in the world, and they are protected under the U.S. Endangered Species Act and Marine Mammal Protection Act and Canada’s Species at Risk Act. There are about 400 individuals in existence in the western North Atlantic Ocean—they migrate between feeding grounds in the Labrador Sea and their winter calving areas off Georgia and Florida, an ocean area with heavy shipping traffic. In the eastern North Atlantic, on the other hand—with a total population reaching into the low teens at most—scientists believe that they may already be functionally extinct. Vessel strikes and entanglement in fixed fishing gear, which together account for nearly half of all North Atlantic right whale mortality since 1970, are their two greatest threats to recovery.
