Anyone watching this on the Discovery Channel?

So far I've learned that a Blue Whale's heart is the size of a small sports care and it's aorta is big enough for an adult human to crawl through!

This is AMAZING!

(Maybe I should've stuck with wildlife biology?)

Thats kinda creepy when you think about it haha.
I dont watch it... but it sounds cool. If they say any other cool interesting things... tell us.

They have some great programming on that channel. Very interesting and educational.

There's some animal in Africa which has HOLLOW hair as a calf so that it can float instead of working hard to swim across rivers!

go to www.planet-earth.com for lots of really fun animal facts! Hahah (yeah, we're losers, I know!)

The Polar Bear has hollow fur too... It is so that it can regulate body temp. though... When it gets cold the hair stands on end and allows the sunlight to beat against its skin to warm it up... (The Polar Bear also has black sking )
