description Fin Whale Overview
A long, streamlined body distinguishes the fin whale, a baleen species exceeded in size among living animals only by the blue whale. Large individuals can reach about 27 meters. Its speed has inspired the nickname "greyhound of the sea," but an equally useful identifying feature is its uneven facial coloring: the right lower jaw is pale, often white or yellowish, while the left is dark. Fin whales inhabit the major oceans and filter krill, copepods and small schooling fish through baleen plates.
Their slender shape and relatively prominent dorsal fin help separate them from blue whales during observation. The species is listed as vulnerable after a history of heavy commercial whaling. Its combination of large size and efficient swimming makes it relevant to readers comparing how different whales travel and feed in open water.
help Fin Whale FAQ
What is the second-largest animal on Earth?
The fin whale is the second-largest animal on Earth, immediately following its close relative, the blue whale. They can reach impressive lengths of up to 27 meters and weigh between 70 and 100 tonnes.
How fast can a fin whale swim?
The fin whale is physically streamlined and highly hydrodynamic, capable of sustained swimming speeds that have earned it the nickname "greyhound of the sea." They can reach impressive bursts of speed up to 40 kilometers per hour when escaping danger or hunting.
What is the distinct coloration of a fin whale's jaw?
A distinguishing feature of the fin whale is its asymmetrical jaw coloration, where the lower right jaw is bright white and the lower left jaw is dark gray. Scientists believe this striking contrast helps them herd schools of fish and krill while feeding.
Are fin whales endangered?
Yes, fin whales are currently classified as vulnerable by the IUCN due to severe population depletion from commercial whaling. Over 700,000 fin whales were reportedly harvested in the Southern Hemisphere alone during the 20th century.
