A blue whale is the largest animal that ever lived on Earth. It is also the
loudest animal on Earth.
Blue whales grow to be about 80 feet (25 m) long on average, weighing
about 120 tons (109 tones). The largest specimen found was a female 94 feet (29 m) long weighing more than 174 tons (158 tones). The females are larger than the
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 car. A
human could crawl through the aorta (a major blood vessel).

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 call is louder than a jet, which reaches only 140 decibels! Human
shouting is 70 decibels; sounds over 120 decibels are painful to human ears.

The blue whale's skin is usually blue-grey with white-grey spots. The
underbelly has brown, yellow, or grey specks. During the winter in cold waters,
diatoms stick to the underbelly, giving it a yellow to silver- or sulfur-colored
sheen; they are sometimes called 'sulfur bottom’. They have a very small, falcate
(sickle-shaped) dorsal fin that is located near the flukes (tail). Blue whales have
long, thin flippers 8 feet long (2.4 m) and flukes that are 25 feet (7.6 m) wide.
