Tonight! Crash: A Tale of Two Species

I just got an email about a show that premieres tonight on PBS. It is called Crash: A Tale of Two Species. It looks like a great show about horseshoe crabs and the endangered Red Knots - a type of sandpiper. The site includes a teacher's guide and some other links - like one for the anatomy of a horseshoe crab. I see they're playing it on our station tomorrow, too, so you might check your local PBS listing!
