What could be more exciting than Shark Week on Discovery Channel? It airs at 9pm Eastern every night this week. You can also see video clips online such as my personal favorite, the top 10 weird sharks.

Be sure to check out the video clip of the frilled shark (above) which was once thought to be extinct. This Loch Ness Monster look-alike has enlarged gills that allow it to swim in the deep sea where oxygen levels are low. You can read more about the anatomy of the frilled shark here.
