Fin whale

About Fin whale:

• It is the second-largest animal species on the planet, second only to the blue whale. 
• It gets its name from an easy-to-spot fin on its back, near its tail.

• It is the fastest swimming of the large whales, known as the greyhound of the seas.

• Distribution: 

• Fin whales inhabit the temperate and polar zones of all major oceans and open seas and, less commonly, in tropical oceans and seas.
• Some populations are migratory, moving into colder waters during the spring and summer months to feed. In autumn, they return to temperate or tropical oceans.

• Features

• They have a distinct ridge along their back behind the dorsal fin, which gives it the nickname "razorback.
• Fin whales have a very unusual feature: the lower right jaw is bright white and the lower left jaw is black.
• Lifespan: They can live for 80 to 90 years and females are slightly longer than males.

• Conservation status

• IUCN: Vulnerable
