DID YOU KNOW?
The largest
animals on earth - baleen whales - survive by eating the
smallest animals and plants on Earth - plankton. A blue
whale can actually be 100,000,000 times larger than the
food it eats!
An adult human
skeleton usually weighs less than 25 pounds, but an adult
blue whale skeleton can weigh 50,000 pounds!
Some arteries
in some whales are so large that a child could crawl through
them!
Whales once
had hair, hind legs and outer ears! Some whales still have
hair and are born with hind legs!
Whales can
"see" with their ears. This is called echolocation
or sonar. Some whales that use echolocation can judge distance
underwater further than you can see through the air!
