At a distance, North Pacific right whales could be confused with humpback whales or grey whales: North Pacific right whales have a broad, smooth back whereas humpback whales have a stubby dorsal fin and grey whales have a series of "knuckles" running down their back.
The North Pacific right whale is designated as Endangered by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). COSEWIC’s assessment of the North Pacific population of right whales is as follows: Although there have not been sightings of this species in the last 50 years in Canadian waters, there have been sightings both south and north of British Columbia waters. Therefore, it is not appropriate to classify the species as extirpated. The total population in the eastern North Pacific likely numbers a few tens of animals.
The Right Whale was considered a single species and designated Endangered in 1980. Status re-examined and confirmed in April 1985 and in April 1990. Split into two species in May 2003. North Pacific Right Whale and North Atlantic Right Whale.
