Tarantula is right though so back to topic, the blue whale is indeed fascinating! My dad saw on National Geographic a documentary about the whale's origins. Initially it was a wolf which evolved into an aquatic version of a wolf when it was obliged to live in the sea (for some reason) so it had to adapt to the aquatic environment. The evolution and DNA modifications led to what we know today as the blue whale ^_^
Off topic, National Geographic <3 !!
