Penguin's feet

I heard about a new book just out called "Why Don't Penguin's Feet Freeze?":)
Have you ever thought about that??
Well, when the scientist explained that a penguin's feet have a unique circulation system that keeps them at a temperature just above freezing---the exact temperature he needs for his environment---I just couldn't help but praise God. He's such a god of detail & perfection, even how those cute little penguin feet can function so perfectly--whoa!
Ponder that one today!
