So, there's this whale that many people call The Loneliest Whale in the World. The whale is named Blue 55 because his whale song is different than any other whale. Blue whales produce a song that is 10-39 Hertz, and Fin whales produce a song that is 20 Hertz, but Blue 55's song is way higher than that, 52 Hertz. No other whale can understand him, and he travels the oceans looking for a mate. Scientists think he is a hybrid. I feel bad for this whale, guys!
