The Blue Whale is the largest animal that ever lived on Earth. It is also the loudest animal on Earth.
The Blue Whale (the whale that can travel all the way around the globe) is the loudest sound on the planet, but they have to speed it up by 10 to be in a frequency Humans can properly hear.

SOUND
Blue whales are the loudest animals on Earth! Their call reaches levels up to 188 decibels. This low-frequency whistle can be heard for hundreds of miles. The blue whale is louder than a jet, which reaches only 140 decibels! Human shouting is 70 decibels; sounds over 120 decibels are painful to human ears.

SIZE
Blue whales grow to be about 80 feet (25 m) long on average, weighing about 120 tons (109 tonnes). The largest specimen found was a female 94 feet (29 m) long weighing more 174 tons (158 tonnes). The females are larger than males, as with all baleen whales. The largest of the blue whales (150 tons) has a heart that weighs about 1,000 pounds (450 kg) and has 14,000 pounds (6,400 kg) of blood circulating in its body. The heart is about the size of a Volkswagen bug car. A human could crawl through the aorta (a major blood vessel).

Blue Whales were abundant in nearly all the oceans until the beginning of the twentieth century. For over 40 years, they were hunted almost to extinction by whalers until protected by the international community in 1966. A 2002 report estimated there were 5,000 to 12,000 Blue Whales worldwide.
