There's a whale, there's a whale.

Have you heard about 52 Hertz whale?

Illustration from Chad Geran's book "Do you know what I am?"

Back in 1992. scientists have tracked this whale for the first time. He has been named "52 Hertz" or the world's loneliest whale because he is the only whale to sing at 52 Hertz frequency. All other whales sing at frequencies which range from 15 to 25 Hertz. This means 52 Hertz is unable to communicate with other whales as his "special language"  is unknown to them. Apparently, this whale doesn't follow any known migration route but is a lonely fellow who travels the oceans alone. At least he has been doing so for 20 years now, since he was first tracked down.
There is a documentary being shot about him, called "Finding 52: The search for the loneliest whale in the world" which is to be released in 2013. Can't wait to see it.

-"What sort of fish are you?"
-"I'm not a fish at all."
-"What are you if you're not a fish? You certainly look like a fish!"
-"I certainly don't feel like a fish!"

Oh, and do you know what "whale tail" is?
