Blue Whales are longer than a basketball court.
The average blue whale’s length is equivalent to two school buses and 25 fully-grown African bull elephants.
Their mouths are big enough to hold 100 people
Blue whales have no teeth, but eat 4 tons of seafood a day, equivalent to 64,000 hamburgers.
A Blue Whale’s heart is the size of a small car, with arteries big enough for humans to crawl through.
Their lungs are the size of a bathtub. They dive for 10 to 20 minute intervals and surface for only seconds to fill their lungs with air.
A Blue whale’s call (188 decibels) is louder than a jet engine (140 decibels).
It can communicate with other whales up to 1,600 kilometers away.
Blue Whales release sprays that are taller than a 2-storey building from their blowhole or spout.
When whales spray water through their blowholes, they are actually exhaling. The blowhole also helps the whale breathe in air.
Every Blue Whale is born with distinct dorsal patterns or distinct markings on their back. These are like fingerprints that help scientists identify them.
Blue Whale males have the biggest penises in the world, with sexual organs that can reach up to 8 feet long (2.4 meters). Blue Whales mate in warmer waters.
