Conservation Status
(IUCN 3.1)

Right whales like the North Atlantic right whale (Eubalaena glacialis) are among the rarest of all marine mammal species. These baleen whales have two separate populations – western and eastern.

North Atlantic right whales eat zooplankton and krill, which they use their baleen plates to filter out of the water.

The western North Atlantic right whale population, which inhabits the waters off the East coast of the United States and Canada, today contains roughly 350 individuals. The eastern population, which was once found from the coast of northern Europe to the northwest coast of Africa, is already nearly, if not completely, extinct

Right whales are slow swimmers and average up to 6 miles per hour. They are known to make brief shallow dives in succession before submerging themselves underwater for up to 20 minute at a time. They usually travel solo or in small groups.

Right whales are also known to emit low frequency sounds that may be a form of communication. When they feed, the water skimming across their baleen plates creates a clicking "baleen rattle." [1
