According to scientists, Blue Whales are the loudest creatures in the world! And those scientists probably had to say it pretty loudly in order to be heard over all those Blue Whales!Why the booming bellows? We have a theory: between all of those chatty dolphins and gossipy groupers, you've gotta speak up!It's a good thing that Blue Whales understand the quietude of a more domestic environment. Not everywhere requires a full-throated yelp to communicate, after all! Is Big Blue in need of a cuddle? Well then he can just bat those eyelashes and the world comes running. No need to worry about your neighbors waking up to a (Blue) Whale of a ruckus. Editor's note: Charles has been yelled at for using the pun in that last sentence.
