Being the largest animal on earth, the blue whale weighs as much as 33 fully-grown elephants, that is about 200 tons. With that said, you can now begin to understand why the heart could measure as big as it does – the size of a Volkswagen Beetle.
That’s the heart. What about the stomach? The blue whale’s stomach is capable of holding a ton of krill (shrimp-like crustaceans) but that’s not all – its daily requirement is four tons of krill! The blue whale is simply a biological phenomenon. Did you know which is the loudest animal on earth? Well, you just reading about it. The sound is produces is enough to rival a jet engine’s!
Their calls register 188 decibels, and if you care to check, a jet engine hits just 140 decibels. Why haven’t you heard this sound you might be curious? The sound is low frequency and isn’t audible by the human ear alone and requires special equipment to be able to. It travels hundreds of miles and is believed to be communication amongst the blue whales. Such a splendid creature this.
