|Binomial name||Balaenoptera musculus|
The blue whale is the largest living animal to live on Earth, not just now but ever.
The blue whale reaches sizes between 69-95 ft (21-29m), although they are slightly smaller in the Northern Hemisphere. Females are larger than males and can reach incredible weights of 90-150 tons.
The diet of a blue whale consists mainly of krill, with some crabs and squid.
They are easy to spot because of their vast size, but they also have a flattened, broad, u-shaped head.
Even though they are so large, they have a tiny dorsal fin which is set far back.
