Crab Spider Tarsi Hook

 
I was watching this spider when I scared it and it dropped with a dragline trailing behind it. At the point this picture was taken the spider was preparing to climb back up to its flower and wait again for prey (before it was so rudely interrupted). I'm usually more interested in watching the side of the creature where the eyes are, but in this case, I really liked how I could clearly see the hooks grab a hold of the silk.

On another note, I just watched "The Root of All Evil?" a program by Richard Dawkins on religion. It was fantastic. Here's Part 1 and Part 2 on YouTube, if anyone else is interested. I sought it out after his interview on Science Friday Talk of the Nation.
