Shark Week 2011 (Day 6)

On the seventh day, God rested.  And so did I last year, so this is the final entry in Shark Week 2011.  Try not to cry yourself to sleep.

Speaking of crying:

SHARK FACT: Sharks do, in fact, sleep.  It seems weird, I know, because sharks would like you to think they are awake 24/7 eating shit and being awesome.  But even the fiercest creatures on the planet have to take a lil' snooze from time to time.  This isn't to say that they are entirely unconscious, though.  It's believed that sharks sleep one cerebral hemisphere at a time, so they can still think about... whatever sharks think about.

Spiny dogfish actually coordinate their swimming with their spinal cord, meaning that it can still swim while sleeping.  And contrary to popular belief, some sharks do not even need to continue swimming when they sleep.  So far, though, there has not been a recorded sighting of any shark sleep-talking.

And, for the record, a shark's favorite bedtime story is Hansel & Gretel.  It just is.
