The fin whale is the second largest mammal in the world, right behind the Blue whale. Growing up to 88 ft or 27 meters, this baleen whale is capable of speeds of up to 23mph or 37km/h with bursts up to 30mph or 47km/h which lends to their nickname, ‘greyhound of the sea’. They have a distinct ridge along their back behind the dorsal fin, which is where they get the nickname “razorback.” The fin whale’s lower right jaw is bright white and the lower left jaw is black, making it the only asymmetrically colored whale in the world. Scientists aren’t sure why this is, but the coloring may help to break up the whale’s outline and make it less visible to the small fish it hunts.
The fin whale generally travels alone or in small groups, and rarely breaches or spyhops.
