-The heart of a blue whale is the size of a small car.
-The tongue of a blue whale is as long as an elephant.
-Blue whales breath through a blow hole located on top of the skull. The blow hole is about the size of a garbage can lid.
-Blue whales have not teeth. Rather, they have 260-400 fringed plates of baleen (a fingernail-like materials) hanging from each upper jaw.
